We are using ZOHO One and have built some simple automation to ensure that the Sales/CRM process properly places relevant files into a WorkDrive folder for each Project.  I've further disabled the "Documents" tab in Projects, and we added a custom field so that our Ops team (who are working in Projects) can easily link through to the folder.

However, if I add an attachment to any Task/Issue in a Project, it gets stored in the default Projects folder (which we're trying to avoid using).  It would be great to be able to customize the root folder for Project document storage on a per-project basis.  Obviously that's happening internally, but making it externally accessible would be very helpful to us.
