Replace enterprise-wide standard meeting request with custom version

[Guest]

I'm new to this area and was wondering if any of this was possible or
not:

I would like to modify the standard Meeting Request form to add a new
tab and have this new version replace the one in use throughout the
organization. (Replace the existing IPM.Schedule.Meeting.Request with
the custom version). Is this possible?

Id so, is there an "easy" way to do this so that we wouldn't have to
worry about touching individual Outlook clients?

Also, whenever we try saving a modified version of this form by
choosing "Publish Form as...", the message class changes to
IPM.Appointment.xxxx or whatever. If there a way to make this message
class become IPM.Schedule.Meeting.Request again or am I looking in the
wrong place....

Thanks for your help!
