Is there a way to add an out of office message for specific techs?

I am new to Web Help Desk, so please forgive me if this is a simple question.

Is it possible to have an automatic vacation message sent to a client when they add a note to an open ticket if the tech has selected "On Vacation" in their My Account area?

We have had some clients who were unaware their tech was on vacation, and would like an easy way to notify them through Web Help Desk for their open tickets.

Thank you.
