Is there a way to do it?
Use layer/layout scale.
Sorry, still kind of new to this, could you walk me through how to do that?
Add action -> System -> Set layout scale
Thank you so much! is there any way to get it to smoothly transition to my desired layout scale?
Yes, tweens for example. In your case a value tween will do.

How would I do that with a system action though?
