I think that is an excellent use of the UIDIGI parameters.  Now
that most areas are upgraded to the New-N paradigm, more of the
four UIDIGI settings are available for this use.  But to make it
work most efficiently,
I would think that the originating Igate would want to make sure
the path does include multiple broadcast hops.  SO therefore it
should probably use a discrete path to the digi that is most
central to the area, and then a single WXMHX beyond that as in
DIGI1,WXMHX.  Would that work?

Because using multiple hop WXMHX,WXMHX hops has the same
RELAY,WIDE dupe problem we are trying to avoid.  But proper
choices can minimize QRM and maximize the coverage.  The problem
is the large number of set-and-forget digipeaters out there...
