Updating Music on hold for Call Queues

There just has to be a better way to manage and update the MOH that plays for the call queues. We have over 200 call queues and it is a royal pain to update each call queue for an upcoming holiday and then again after the holiday. It takes hours! It would be nice if you could create MOH sources (at minimum of up to 30) and then you just point to that source for the MOH you want applied. We have over 12 different divisions in our business, that is 12 different MOH productions. Please consider this so I can stop dreading the holidays. Thanks!
