Yes, you can most definitely use Room Lighting for this. Just set up a new RL instance which includes all your lights you want to control and set the desired settings for each of the lights. Then at the bottom of the main RL window you have a field called “Control with Activator Device”. Type a name in there and the app will create a new device which you can control with Google Home.
Once you have created your first instance and found it working as you’d like, you can clone this instance to make a copy that you can use as a template for the next instance.

Good luck!
