Delete older packages automatically from hard disk

Hi,
is there an option to delete the old packages / activites during a deployment from the robot runtime server? Our problem is that we always run out of hard disk due to huge robot-user folders. Each robot has all old packages within their user folder. It would be great if I could configure that only e.g. the latest two packages are kept and older ones are deleted. Otherwise I need to do this manually each time we run out of hard disk.

Thanks and best regards
David
