"I'd REALLY like to be able to add more tags. I would like to be able to mix and match tags based upon use cases. For instance: Campaign 1 (tags: abc.com url, gmail account, buyers); Campaign 2 (tags: yahoo account, 123.com , gmail account, sellers); etc. This way, I could filter specific addresses from specific websites as well as match specific criteria. @Jeremy Redman , is this something that is possible?" - Michael Finley
