How do I group objects and scale them in my project?

like, specifically grouping and scaling in the project, not during gameplay. I want to take one existing level and scale it down to create the illusion of zooming out the camera for that level without affecting the window size of the overall project, but currently everything scales from its own origin and I can't find a way to group and scale them with respect to eachother.

If you are using only one layer, you can use the system action "Set layer scale".

If you are using more than one layer, you can use the system action "Set layout scale" for your current layout.
