Multi Asset Rotation

I’m new to the Revit interface and full disclosure despise Revit in general. I am working on a context model and would like to place a variety of cars along the side of the street. It seems like the Multi asset option would be perfect for this but there is no way to control the rotation of the assets. It’s either random or whatever the default 0 degree setting is. I need all of the cars facing the same direction. Is my only option to either manually place each car?

How do I select the group once the placement has been confirmed?

Multi Asset placement isn’t useful for placing elements along a path with the same orientation. Just place each asset individually.
