Is it possible to have the changes that have the same checkin comments be
grouped so that there is only 1 line. Now, if I change 10 files for a change, I
get 10 times the same comment in the changes web page.

Suggestion:
If you have access to the user who made the comment, you could do a grouping by
gathering all of the consecutive commits that fall within X second(s) of the one
before. Then sort the list into multiple lists by user. Each of the resulting
lists would be your "changeset" grouping. (Depending on your network, I would
think X would be <= 1 second.)
