Mass clearing the Waiver Queue

I think we need a "CLEAR ALL" button on the waiver queue on the admin side. Under additional settings where Admin can see all the waivers in the queue. Ours has gotten quite backed up and ones have been sitting there for days now. 

Maybe they expire after a certain amount of time? Or, when we delete them after a certain amount of time and the player finds the email in their inbox days/weeks later the link says it has expired instead of it can't find the page they're looking for? 

Does that make sense?
