Program button for sensitivity
 

We use a PGP gateway and have need to tag emails as "Sensitivity:
Confidential" on a regular basis. This is annoying in the default
manner.

We created a macro to open a new message that is already tagged, but I
need more. I need to be able to change messages on reply to
confidential as well.

Really what I need is an option like the "high priority" icon available
in all possible situations. Is there a way to do this easily, or an add
on that could do it? I do not have a VBA or Outlook expert on staff to
turn to. TIA
