Suppliers And Vendors In Multi Vendor

One question that arose when I was studying the add-on suppliers is that when creating a supplier it is necessary to indicate a vendor. Isn't possible to create a supplier without any vendor associated to it?

I thought that this feature could be used to emulate a scenario when you have a company that deliver products in place of others, like in a dropshipping, but if a supplier need to be associated to a vendor and can only be used by that vendor, this doesnt make much sense.

I have the same problem. Did you find any solution to this?

I think custom development is necessary.
