Conveniently adding art layers after Event Sheets are made?

The title could not properly fit what I was trying to ask.

Imagine this scenario: I make a game. This prototype build has three layers: Background, Game, and UI. Very simple. The Game layer has a player that shoots stuff. It shoots stuff by Creating an object on image point x On Layer 1. I do this numerous times for various things in the game layer focusing around the On Layer x action.

Now the prototype is shaping up into an alpha/beta, and it's time to make the art better. I want to add Parallaxing background layers. This means that I need to add multiple Background layers under the Game layer. This means that the Game Layer is no longer Layer 1.

When I slide the Game Layer around with other Layers, it doesn't change the value for ~On Layer actions. Is there any convenient way to move all of my "Create object on Layer x" functions to a different layer number at once?

Instead of using layer numbers use layer names. Then you can add as many new layers as you want without needing to update anything like that.

Thanks! I wasn't aware you could do that. This is a pretty important thing to know ahead of time, I wish the really popular beginner tutorials mentioned that.
