Clear Application Learning List on SEPM

Is there a way to clear the list of applications that appear when you enable Application Learning in the Communications settings? I turn on app learning and add the exe's that I need and set them to "log only" then I turn off application learning for the group. The list is currently pretty long when I open the Exceptions policy and select "Windows Exceptions" then "Application". Just looking to see if I can delete that list somewhere as a housekeeping measure or if the list just continues to grow as you enable Application Learning for new groups.
