more collision questions`

is there a way in which i could import say 2 walls side by side, then make it to where you can have collision for both of them even though it came in the same model?
like instead of having to make it wall by wall and setting collision for each and every wall, can i make it to where i have a hole building and have collision?

I think it would cause less headaches to split it into two walls.

Any reason you need to know if the player is touching two walls? Maybe there's another way.

alright, thanks, just thoughtt hered be a shortcut >< lol
