You can't get UserA to set the username part to anything but UserA but you
can enforce use of group "support" by setting the "setgid" bit on the
directory.

(chmod 2775 <dirname> or chmod g+s <dirname>

Then set your umask to 007 so any files created are 770
(-rw-rw----) or to 002 if you want "others" to have read
access. (-rw-rw-r--)
