Exchange room autoreply with custom data

Hello,

is it possible to create a Mailbox Autoreply in Exchange 2010, which will include date and time?

I every autoreply we now have:

http://intranet/room/

We want the link to be more dynamic like:

http://intranet/room/?room=GUID_FROM_AD&date=2012-12-20&time=10:30

Is this possible?
