It seems there’s some confusion on how to edit, delete, and reorder destinations and purposes. So here’s another blog post to help you out.
Simply select Businesses in the Presets. Then select the business that has the destinations and purposes you want to edit. You’ll then be able to edit the business name and type/rate, as well as edit/delete/reorder the destinations and purposes for that business. It’s that easy!
