Our development staff are using activities for tracking moves management. We've created a custom set of "moves management action types" and have added those to appropriate civicrm activities. I can't, however, figure out if there is a way to assign custom fields to the "Send an Email" activity type. I'd like to be able to assign the same action types to the "Send an Email" activity type for reporting purposes.
Anyone have any ideas how to do this, or an alternative approach?
