Is there a better way to do collisions for a static mesh?

I made a few house meshes in 3DS Max and I was wondering if, after importing it to UE, is there a easier way to add collisions than having to manually move boxes around, that actually works? (obviously auto convex doesn’t work at all for “complicated” objects like this)

Nevermind, figured out I could go to the tab called “Static Mesh Settings” in the mesh editor, and change “collision complexity” to “use complex collision as simple”. Apparantly pretty taxing as it renders the mesh twice, but works great for me as the houses are semi low-poly.
