Saving custom zones

I want to be able to save custom cleaning zones on the map, instead of constantly having to recreate them when I want to zone clean. How can I do this? There are no options to save them. This is a primary reason I rated 4 stars on Amazon instead of 5 stars. The app really needs some work, and I sincerely hope it will receive necessary updates.

Hello,  you can add a shortcut, where the areas you select will be permanently saved.
