Problem: there is no easy way to identify opt-outs from each campaign. They are lumped all together in the one list and "apparently" I can't filter for date added or campaign sent.

The simplest option would be for the opt-out list to contain these identifiers so that I can send a net list of contacts to my team to update our database (because we don't have an integration).

But to also be able to create an opt-out list form the contacts section of where the list is stored.
