I would love to see an option when preparing to send emails for me to include several groups/saved searches (like it is currently) but to ADD a EXCLUDE option for to remove other groups from that email. For example, I want to send several donation solicitations. But I DON'T want to include people who recently made a donation or perhaps a group of people. So when WA populates to who it is being sent to, it would take my recipients (for example 100 people multiple saved search or member levels) and then remove or not include people who fall into another category such as those that made a donation in that time frame (for example 15) and then the email will be sent to those that remain (example 85 people)

This would be fantastic in the advanced searches for members too. It is so hard to get what I am looking for because it is ALL or ANY. If there was a ANY of different search options AND then a EXCLUDE to remove a subset of people that are in another category.

For example, I have a screenshot of iContact.
