Allow to select several areas for Macro with Shift

[Kromster80]

Map editor - macros - unless I am missing something, we cannot currently select several areas at once. What I would love to see is the ability to hold down the Shift key and select like 15 areas across my map and generate whatever feature I want on all of them at once. Having said that - after hundreds of hours of building maps without any terrain/feature generating tools for other games, I LOVE macro functionality as-is already!
