How to create 2. layout without using the default layout(.swig)?

[webcultist]

As the documentation says:
"By default, the layout template is used by all other templates."

I would like to use a second layout, totally different to the first layout, but when I create a second layout, it's always included in the default layout. I can say "layout: false", but that way I have NO layout.
Saying "layout: layout2" it's always included.

Is there a way to really use a totally different source layout without including them in each other?
Thanks and sorry if the answer is very obvious.
