Is it possible to customize reports?

The information and format of the activity reports isn't very helpful for our needs so I'd like to be able to customize the exported report. For example including a column with Email when "Request user data" is used. Another thing that would be helpful is separating the filename and folder path into separate columns to make for easier machine parsing.

Lastly, is there a way to schedule the same report to be run periodically, for example weekly? Ideally I would also be able to have it emailed to me.
