Archiving old Review 360 projects?

Is there a way to archive old Review 360 projects? My team publishes a lot of courses there, and it's particularly difficult to find specific courses - barring search - without wading through every project we've ever published.

It's particularly cumbersome when you're trying to publish a from storyline and you know there's a course in Review 360 already, but the is unwieldy.

We don't necessarily want to delete projects, because we don't want to lose the comment history. We're just looking for a way to get the older projects out of the way. I guess we can create a folder in Review 360 and just move them there, but that doesn't necessarily fix the Storyline target problem.
