The new feature for stands

So we finally got the possibility to make a stand exclusive for one Airline. And that is cool.
I want to keep building on this feature.

What i think should be added.
Atm we can only make a stand for all airlines or only one. Not 2,3,4 or so. One Or all.
I want check-boxes so i can add one stand for a few airlines.
In the long run it would be cool to be able to also choose what kind of aircraft can park at a stand. I think that would be a cool feature depending on what of airport you build. Again, you press the stand, and then a button on the menu for the stand. Get a list with all aircraft and check boxes so you can choose.
