Foobar2000- How to quickly switch layouts created using ColumnsUI

I started experimenting with the latest Columns UI. It lets you create multiple Layouts but I cant seem to figure how would I go about quickly swapping layout in the future?
The only way I seem to achieve this now is by accessing the preferences window, then display, layout.
I am looking for something like a hotkey, direct button on the UI, or a command line option to trigger a specific layout.
Any help will be appreciated.
