In Sharepoint Online, I have added Document Library View web parts to most pages. I have also added a metadata (column) called Page to all Document libraries.
The idea is for the Document Library View to filter the site's documents so it only shows documents belonging to the page.
So far, so good. The problem is that when uploading a new document, the metadata Page has to be filled in manually by the user.
What is the easiest way to make this happen automatically, across all pages? Should I create a custom Upload form and assign it to all Document Library View web parts?
