Can you use the same game objects to set a portrial canvas *and* a landscape canvas?

I have an app that has multiple displays for information, and in portrait, the orientation of the panels have to be different, so that led me to think:

Can I have either a separate scene or a separate canvas script that can be set completely independently (only visual layout) while retaining the same references, so I don't have to double up each object and switch between the two?

I'm not sure how to phrase it correctly. Hopefully, that makes sense. Thanks!
