A suggestion:

put a unique string in the comment field for your repeating projects or actions that you are unlikely to use elsewhere. Now, set up a window that searches for completed projects (if that's where your repeating actions are) or completed actions (if only actions repeat, not projects) with that string and save it as a perspective. Pull up that perspective once a <insert appropriate interval here> and delete the old ones. At least that way you can use OF's filtering abilities to get rid of the chaff.
