Make it possible to create groups of doors with a hotkey or interface button

[asanbr]

There are many situations - mostly raids, manhunter packs and toxic waste - where I shut all my people inside for some time. It is annoying to have to manually select all the doors and forbid them to acheive this. Could there be a better way to set a group of doors as "perimeter" and then easily enable/disable all of them?

While writing this, I realise that restricted zones may be the better answer to my question (without changing the game). Never thought of handling it like that before. Will try.
