factory monthly output increase

[grampybear]

 The ability to increase monthly output of a factory all ready in game as consuming factories are added. perhaps this could be done as a percent, as each new consuming factory is added the monthly output of originating factory is increased. Example; one furniture factory should be able to supply more than one end user of furniture without destroying the furniture factory and rebuilding, however this output quantity is not known until new consumer factory is added. Thank you
