SelUnqSubUnit now accept two new optional parameters:
Area <AreaUID>
and
Region <RegionUID>
Like in
SelUnqSubUnit Napoleon; Region $Paris
The previous parameter supported was CondSkip, which skip the command if the SubUnit selector was already valued. You can evaluate if it is valued with the EvalSubUnitSel command (no parameter).
Reminder: SelUnqUnit is deprecated.
