Hello again 6StringJazzer and Jbeaucaire,

Sorry coz the file is for internal purpose. If I own it personally, I'd be glad to send or upload it here.

Anyway, what I mean is some unique identification code inside those sheets that will be printed to be called upon when the toggle button is pressed. That's the ideal option I have in mind.

Furthermore, when the need to add another sheet to be printed, I will just copy a Printed sheet with the code in it and this new sheet will have its row hid/unhidden when the toggle is pressed.

On the other hand, JBs suggestion's are fine with me, putting the # sign in the sheet tab or a key cell, if you think that's not possible.

Thanks again!
