I'm working on my first ren'py project where you play as two characters, one during the day and one at night. The thing is, I'd like the dialogue choices to look different depending on the character you're playing, and I can't for the life of me work out how to do it.
This is a screenshot from the game, with how I want the choices to look - Calliope's choices are on the left, Len's are on the right. I just don't know how to actually action this when it comes to coding.

Thank you in advance, and I'm sorry if I've posted this in the wrong place or something, I am a newborn baby of a ren'pyer
