Helicopter Schematic idea(s)

Just thought of this and hope the devs might consider: it certainly could be advantageous for those seeking a much more trauma-heavy hospital that helicopters are not owned by the player, rather the hospital merely purchases landing pad(s).  

These pads should be expensive (to be a goal for players closer to later game)
Enable more than one helipad (the cost of each additional could be very steep so as to reward larger hospitals and later-game players)
Patient flow via helicopter allow for higher numbers than ambulance (set 3 per ambulance) for 6x3 =18
(this would also be a reward for those who have established a robust trauma patient capacity and could render helicopter patient levels closer to 25 or 30.
OR  **perhaps much like an event, one gets a dialogue announcing a potential medivac patient that the hospital can either accept or decline** and thus give more control and flexibility to the player in matching their hospital's capacity.

just ideas.
