Set up your own base of products!
Thinking a bit, I came to the next:
1. The realization of this possibility is not as complicated as it seems
2. I have not seen anything like this in other products
As a result, the function Product Insert (version 126.96.36.199) has the ability to edit the list of documents used by the function.
I did not stuff this window with various "chips", such as searching for documents or grouping them into sections - all the documents go in a solid list. I think, the opportunity will not be so widely in demand, so it did not waste energy on it. Who needs to disable some documents - he will cope with this and having an ordinary list =)
