Now you can merge two gift designations together.

1. Go to Settings/Gift Designations
   
2. Click on the gift designation that you want to get rid of.
   
3. Click "Delete & Merge" at the bottom of the screen.
   
4. Select a replacement gift designation from the list.
   
5. Click the red "Delete & Merge" button to confirm.
   

All the donations that were in the original gift designation will be moved over to the replacement, and then the gift designation will be deleted.
