Functionality Request: 'Fall Off' (Accessible, but Unpublished)

So the idea is that for fundraiser that have end-dates, either they can be tagged in such as way that they're visible on 'completed fundraisers' only, or are identified by a 'Complete' type of tag.

As it stands, I do not want people forget that they helped to raise $X for a fundraiser, but I do not want that to be on the same page as active fundraisers.

Is this possible?
