Currently through SellerActive you have the ability to list to Jet.com and Walmart however there are limitations on what you can edit and manipulate. Most of these restrictions are actually due to the marketplace settings and information in place on the marketplace directly prior to you creating any new inventory items.
For both of these marketplaces you must provide a Product ID (UPC, ASIN, EAN, etc.) and this Product ID may have already been listed on the marketplace. Each marketplace takes this provided Product ID and matches it with all previously stored information. If the Vendor of the specific item has already listed the proposed item and included multiple images and a detailed description, then that will impact the "end result" of your listing attempt.
Ultimately, you are able to attempt to update Jet.com or Walmart listings that you have listed through SellerActive however there is not a guarantee that this information will be updated on the marketplace. You may need to reach out to their respective support teams in order to get information updates appropriately however you would run into those same issues even if you listed to the Walmart directly or if you listed to Jet.com using another third-party.

When I am listing a product through SellerActive, it requires me to input a description and image. If you are saying this information will not affect the marketplace in specific instances, then why am I required to include that information?
Unfortunately, even though these fields may be overwritten, they are required by the marketplace to create a new line item within their system. If you are to list a product directly on Walmart for example (sans the "Match Tool"), you are required to include description and image URL as well. While this may be tedious, you can include a limited Description if you already know that this item is available for sale on the marketplace and anticipate that the previously provided information will be emphasized. On the other side, if you are the only person selling this specific item then you will want to include as much information as possible to accurately describe the item.
I do not see the item I want to sell in the marketplace currently, is it safe to anticipate that my image and description will take precedent?
Searching through Walmart inventory is difficult provided the search functionality is "title based." The item could be under a different title or something not anticipated. Also, the item could have already been listed however it is out of stock and not visible within the Walmart search tool. Your only guarantee (so far as we can tell) is if you list with a unique Product ID for your products.
I am a Private Label seller. How can I guarantee that I am the only one selling my product on Walmart.com?
From what we can see, as long as you have a Product ID and the basic required information, anyone can sell any product (sans certain banned items). We have seen Private Label sellers who noticed their items being sold with incorrect descriptions and images.
The best workflow for this is to list the product through the SellerActive or Walmart with all of the valid information and then reach out to Walmart Support to adjust the necessary information. There does not seem to be a way to limit other sellers from selling your products; however, Walmart Support (or your personal Walmart contact) may be able to expand further.
