Create a Listing on PrimeLister Inventory

I’m trying to find out if you will be adding the capability to create inventory from your software. I know I can import, but I’m looking for a cross-posting product that will allow me to begin my items and then post/cross-post to the most advantageous selling site for each item. I currently use Vendo, in which I start my listings and then post and cross-post. I would switch to your product if I could do the same. Meanwhile, I will need to keep using Vendo and only subscribe to your automation software, but not your cross-posting one.
