reservation emails based on specific courts booked

We have a few courts spread across different areas but close enough that we don't want to have different sites listed. We'd like to give different instructions for going to the courts based on which court people booked. For example, we have one main site and another site within 10 minutes walking distance with a different front desk. We don't want people to be confused and to go to the wrong site, so I'd prefer to send different messages, but currently there is no way to change the message based on which court was reserved. Until this is fixed, we'll be forced to have an extra long message explaining the location of both sites.  I imagine other facilities face similar issues and would prefer to send specific instructions to get to the court that was booked.
