Affecting 100 buttons all at once

That’s what i need to do!
Switch on or off or trigger a gotoAndStop in 100 instances of the same button symbol by pressing a ‘reset’ button…
Is this even possible.?
At the moment I can only affect 1 button!!

thanks for help… sorry if it seems like a dumb question, but it’s friday and my head is going bongo-floyd!

thanks
