after playing some years through a game and stuff I build more airports/train stations/bus stops/deposits...
but sometimes I want to expand this building or improve.
but there are just loads of planes, trains, trucks/busses coming in a stream that I can't even begin to stop, by the time I'm done the company will be bankrupt

so the Idea was to be able to put for example an airfield on hold, meaning it will reject all plains from landing and redirect them to the next thing on their list. this way I can destroy that airfield quickly and rebuild a better one in it's place.
other idea was to be able to upgrade buildings, the first thing is the same, redirect/reject all incoming, but instead of having to destroy an airfield/deposit/harbor/train station. (if there is enough room to) I can upgrade the building, this way the waypoint for all the vehicles stay, you can easily reopen everything by flicking a button to "accept" again. and everything still has the waypoint in it's route.
