With the recent expansions of SAR and Airports I've noticed alot of stations are very similar, and although part of the game it can get rather tedious to do the same action 4 or 5 times.
Suggesting the ability to copy and paste stations so it takes the station size and units in it and gives you the ability to place it elsewhere, obviously for the correct amount of money.
Would be happy to see this added as a premium feature if needs be.
