Dear @caria,
Sure, it should work for the Edit form as well, just add +1 to the ID. But as I've said, this might present issues on the last item. Let me know how it goes for you.
I would like to recommend adding the ability to copy a document to a new name, the regex the document to replace wildcards with information from a list item.
Hello! You can specify the name of the copied file in the destination URL. It is possible to compose it dynamically using the SP list data and a regular expression replace, then pass the output string as the destination URL to the action for copying the file.
Microsoft changed content type propagation to sites. Can you add this new PnP cmdlet? Then you could set up a site with a flow, then get the content types to update:
Add-PnpContentTypesFromContentTypeHub
Background: What’s changed in content type publishing
And
Add-PnPContentTypesFromContentTypeHub | PnP PowerShell
Hello! We added the suggested action to our road map.
