So I had an idea that could be easier than adding a new plane entirely. Some people have suggested this in the past for 737. Could you add multiple variations of airplanes. ( EX: 737- 100, 200, 300, 400, 600, 700, ETC or A318, A319, A321. )
This would be a nice add on as we could still fly the current aircraft but have multiple versions of them.
