Emails

When we have multiple "clients" we have added to a design board it would be great to be able to select who is receiving the emails when we "re-submit designs to client". For example if I add a new individual I am forced to email the whole group again. Other times I just want to email one person and not the whole group that is tagged as clients. Deleting isn't an option because it erases historical activity for that individual within the project.
