Hi!
Our organisation uses the prospect plan participants area to include people who may not be prospects themselves, but are still part of the plan e.g. contacts, friends, employees.

Since these people are not necessarily donors or people who have consented to receiving marketing material, we would like to be able to exclude them from Marketing Efforts. I cannot figure out how to do this because creating an Ad-hoc Constituent Query will only allow you to create a selection of the constituents who are the primary prospect. There is no ‘flag’ for prospect plan participants on constituent records, this field only exists under the Prospect node which cannot be used in a Marketing Effort.
Has anyone else come across this issue and devised a solution? Any help is greatly appreciated!
