signature, disable when forwarding?

[DrPink]

I'm sure I once saw an option, where you can set up your signature so that it will add a signature when creating a message, but won't when you are forwarding or replying a message.
We are using both notes 6.5 and 8.5.

Any ideas?

Real life needs a mucical score.
