I would suggest for address settings -1 isnt used (as for other settings it
typically means disable also for your above mentioned it could not be very
flexible) but some expression (take inspiration from spring spel) is
implemented could be used to deduce the calculated. So if you wanted to have
different groups you could split up the allocation by a percentage or some
other calc. ---
