Single use function in Sugarcube

ReynardFox

I'm kinda new to this, and I'm wondering how I could make a function that only works on a specific page? I don't think I can use a widget bc the function would replace a specific div in that page. Right now I'm just copy/pasting the code chunk and replacing the relevant parts, which looks really ugly and is hard to manage.

That's a bit vague. Some additional details would help.
