It would be very useful to be able to create a customizable list for pushpage. For example, we have an email going out to families coming back for the next school but we can't exclude families not returning because they are still listed as current parents/students.
I need exactly this right now and I'm having a hard time figuring out how to do it! It would be really helpful to be able to easily choose from more types of groups!
Agree, while we have found query-based workarounds for most of these cases it would be fantastic to be able to remove individual users from a distribution list for an individual mailing instance.
