Limit the permitted filetypes in a board file column

The Files column on boards is very versatile. I’d like the ability to limit it’s versatility, requiring that only one source (e.g. Google Docs, Monday WorkDocs, etc.) be permitted on a given board. In my use case, we have a requirement that all documentation relevant to a certain board be within Google Docs. The current Files column allows many other file sources to be linked, which violates our standard (both a compliance issue as well as a search issue when outside of Monday).

Thanks for the consideration!
