Two seperate ui-lovelace

I’ve been testing out two different dashbords now in the RAW editor. One for iPad and one for iPhone.
I wanted to clean up the code a bit and I made a button_card_template. Last time I checked it was not possible to do !include button_template.yaml in the RAW editor.

So then the question is - is it possible to make two different ui-lovelaces? So that I can have one for the iPad and one for the phone? I tried creating another called ui-lovelace_iphone.yaml. But it did not show up in the sidebar.

Yes. You can provide different view to each user
Make different user for each device
