Date filter in Perspective?
 

Every week, I deliver a report that I generate with OmniFocus. One part of that report is the stuff I've done in the last week. I've set up perspectives that show me all of my completed tasks and projects (sorted by date), but they are getting laughably huge. Is there any way to build a filter in so that I only see stuff from the last week?

Not pretty, but the two ways I do it (for two separate perspectives):

1) Archive "today - 7" before viewing the perspective
2) Group by completed, expand only the time periods you need, save the perspective to preserve expansion
