Content removal task against My Folders / entire Content Store??

[unalias]

Okay so I just upgraded 8.4.1 to 10.2 and I was very excited about the content mainenance task and the ability to set both retention times and to remove old content with a single job. We've had over 3000 users for 7+ years and let's just say the content store has gotten a bit out of hand.

I want to perform a sweeping removal of all output versions older than 12 months (after letting the users know, of course) but much to my dismay I see that this is a task only available against the Public Folders.

How do I get this maintenance task to run against the entire content store and hit the My Folders content? Can I? Why is this not an option, Cognos?
