I originally posted this in the Wish List but having watched the first Marionette tutorial this seems like an ideal project for marionette. What I would like to achieve is outlined below.   Have you ever just finished a housing layout with say 300 houses plotted and numbered from Plot 1 to Plot 300 and the client comes back with can we turn Plot 6 into a pair of semi-detached houses. That means renumbering from Plot 6 onward. Even with the number stamp this is tedious.
