Feature request: Mobile client delete files after upload and after a configurable number of days


I would like to propose an option in the mobile client for deleting uploaded image files but after a configurable number of days.
The use case is for people who take pictures, screenshots or download files but would like to have the files on their phones a few days after created in case they need to use the pictures but older file are not important to have locally but only backed up in nextcloud.

Currently you have the option to maintain the file in the same path or move to a new location at sync time but if you could delete syncronized files after X days this could avoid needing a different application just to delete old files and also avoid the danger of deleting files not yet uploaded to Nextcloud.

i hope someone could find this useful too.
