Oh! I didn’t realize it was you, hey! Haha!
You’ll just put the labels right before the script you want it to lead into. The labels essentially function as a checkpoint in your story and won’t impede the flow of the story at all. Above your CC code, for example, you’ll put:
label character_customisation
Then it’ll automatically jump to your actual code. At the end of the CC code, you’ll put something like
goto main_menu
And have “label main_menu” at the very start of your story so they can go back and play the story after they’re customized. Does that kind of make sense? I can send you a video on Instagram if not!
