Timed or reversed approval queue?

[TheGGMachine]

Is there a way or an addon that can reverse an approved item from the approval queue after a certain amount of hours or days? How about a timed or temporary approval? Is there a tool or addon that can see and undo(remove) previously approved items from the approval queue? Like expires and is removed or undone? I'm needing to be able to reverse approvals either after a certain amount of time or undo them by seeing a list of ones that were previously approved.

I've been looking and I may have missed something as I'm still new. Please help or inform me. Thank you bunches!
