Option to only move attachments based on filetype or through user input

[ebw44]

First, thank you for a great extension.

Is it possible to have a different renaming rule based on filetype/extension or by asking user for renaming confirmation/validation? My use case is the following:

• I use zotfile to move files (pdf, html, zip, mp4...) to my OneDrive folder and create links.
• I use the renaming of pdf, html snapshot so I can find papers on Onedrive web interface or computer without zotero installed.
• The renaming of zip, mp4 is not really convenient. So for those, I change the extensions.zotfile.disable_renaming to true. I also do the same when I have multiple pdf for the same item (for example one pdf for each chapter of a book). This is a bit of a manual process, is there anyway to improve that process with the current version (5.1.1) of zotfile ? If not is it a feature that would make sense for other users ?

The comment on multiple pdf for chapters of a book is related to #296. And the option proposed to have the original file name as a field you can use would solve better the case of multiple pdf for the same item.
