Is it possible to create a safe zone?

Hello, first of all, thanks for the work and sharing it so I can use it.
I have a problem. I don't know if you could help me.
Could the safe zone button also be added? When they enter a safe zone, does it also change?

Hey, yeah i like this idea, i will add it for you

Thank you for your response, sir. Would this be possible? If I can help you with anything, just let me know. I like testing, looking for errors, and improving things in general.
