Is it possible to use multiple collision objects for the same tilemap?

I have a tilemap with two tiles: stairs and wall.

Then I added map gameobject with my tilemap and colision_object(trigger) and defined the collision shape (my tilemap).


My stairs logic works fine but i dont know what to do with the walls (it requires statics object). Is it possible to use multiple collision objects for the same tilemap?

The only other way I see is to create an additional object with multiple static collision objects and draw it over my map.

What approach do you use to create physical walls for the tilemaps?
