A Way To Delete Friezes Tile By Tile?

The frieze will be placed on the outside of the house according to the rooms connected on the inside; so if you want a specific frieze to only cover a small piece of the façade, make a temporary room connected to the outside wall, place the frieze, and then remove the room, I mean, the walls of it that is not the outside part. I play on PC.

I did not know about the shift click, thank you.
