How to make 2 choices in a different style?

Hello!

Currently, my game looks like this:

In my sketch, I wanted to do 2 different styles for each option, or more precisely, change the background image of the second option:

(This is the only choice style I will have in my game and I will have it multiple times.)

However, I'm not sure where to start with this, I guess I suppose I have to add the other choice GUI in the GUI folder, but you cannot have 2 "choice_idle_background" in the same folder.

I just edited the current Renpy code/ the GUI folder and added my fonts, background, and so on...

How would you advise me to go about it?

Thank you for reading!
