How do I change the layout size at runtime?

I have the entire game running in one frame, and changes between "levels". I just want a way change the layout width and height at runtime, but I can't find a way to do it. Switching to a new layout is just way to prone to errors with the way the system is built right now.

Looks like this is possible with scripting:

construct.net/en/make-games/manuals/construct-3/scripting/scripting-reference/layout-interfaces/ilayout

I'd just enable unbounded scrolling, and impose your own scroll limits.
