Want: Knowledge Portal for Custom GPTs

I have 20+ custom GPTs that I use for work and sometimes I’ll make a slight change to a file that each one has in their knowledge base. It’s annoying having to go into each one, delete the file, and reupload the new file. It would be neat if I could get a knowledge base portal where I could upload a file and select which custom GPTs I want the file to go to, as well as remove current files.
