Closing Appeals?

Hello all!

I am currently attempting to clean things up and set up all our appeals/campaigns for the new fiscal year. I've managed to add everything I need, but we have some serious clutter from prior appeals not being closed.

Does anyone know if there's a way to have this done automatically corresponding with the appeal's end date? As of now, I've been manually closing each one, which is eating up a huge part of my day. 

Any suggestions or tips would be much appreciated!
