Extra window layouts for Easy Arrange in Dell Display Manager

I am the proud owner of a Dell U3421WE monitor. The Easy Arrange program in Dell Display Manager makes it easier for me to organize multiple applications smartly on the screen.

I need a layout that is not in the drop-down menu.

Is it possible to create custom layouts yourself?

If so, where do I find it.

If not, is it possible to submit a change request for Dell Display Manager?

I am using Dell Display Manager 2.0.0.1135
