Allow file upload pull requests for non-push users

I want to be able to allow people who do not have push access to upload a file and submit it as a pull request. Is this possible?

Hi there! :wave: Welcome to the Community!

The usual way to accomplish this would be to have the person make a fork, upload their file there, and then open a pull request!
