Just a cool idea I came up with... 
An example to help - a player has 3 separate cities they have coverage in, each grouped with a separate dispatch.
On the mission list towards the right of your screen, where all of your missions are listed if you toggle the far left option, alliance missions etc... Can we have a separate button for each dispatch building/zone?
A player may wish to dispatch units to missions only in a particular city at any given time. The player may for example know that they are out of ems in a particular area, meaning they wish to focus dispatching in one of their other cities. Instead of going through each mission and finding out where they are, a simple toggle switch to enable/disable 'dispatch zones' would make this process a lot easier and quicker 
Thoughts?
