Set Complex Collision to All Objects in Level


I’m new to UE4 and I bought the polygon city pack from the marketplace. I’m importing some of the models in the map to a different 3D software and I found that all the models don’t have any collisions. I found that if I edit the static mesh and check the complex collisions in the collisions tab, it works. However, it’s really tedious to do this for every model in the map.

Is there a faster way to do this?
