How to make a showroom

I am trying to make a showroom, but I do not know the system it has, I do not know if I have to generate the pit.pprque the AC showroom comes out but not where the pit and the CM showroom is or comes out.que is the one I want to do to move and put cars without it being a circuit. Thank you

 

its just a basic track kn5, spawn point at center 0,0,0
no pit/start dummies needed

 

I refer to the showroom of content manager that is the one that you can move the car with the T key and put more vehicles.I made a kind of esplanade with a garage I put pit and in the showroom of assetto works, but the car I can not move it in that showroom. It would have to be the showroom of the content manager
