Would it be possible to delete files over a certain size from tickets but have the tickets remain?

I see it has already been requested to remove the user details but to retain the tickets, this is the most important request for me.

My data storage is very low but my file storage is high, and ultimately I'd like to keep the tickets for reference purposes but remove the user information and any video files they have sent us (hence the file size request).

Long term, this would require three deletion schedules at the same time. One for the user (to comply with GDPR), one for the attachments that exceed a certain size, and one to remove tickets over a certain age.

This could work like the trigger system, so that each time the deletions happen an order is followed.
