I'm hesitant to add an option in the Connectivity filter to do this.
Instead, I can imagine uses for a volume computation for
surfaces/volumes labeled by a RegionId that isn't necessarily assigned
as a function of connectivity. Instead, I would prefer to create a
separate filter that computes volumes for each RegionId in the input
dataset. You would feed the output of the Connectivity filter to this
new filter and get the volume-per-region information you want.
