I have created 4 different kinds of Suppression lists with various names on different criterion. Since I was a beginner, I did not know the best practices, however, now everytime when I run a campaign, I have to add 4 extra Target Lists to ensure no suppressed names get the email. I want to merge all the 4 suppression lists and make them one. there are too many contacts to be able to do it manually. Please help with a solution.

I noticed one more post in Sugar with the same concern in 2010 but the issue is still unanswered. Please help !

Thanks !
