But I can’t. please help

thats not a feature, you might be able to make a feature request though

Yeah, you can’t add checkboxes to arbitrary reporters. We’ll put that feature on the “maybe someday but don’t hold your breath” list. :~) You can make a variable named COSTUME # and then


only with your block name instead of “costume #.”

I meant making a custom block that has a checkmark that makes them display like a variable

yeah, that’s exaclty what he was talking about.

ok
