it would be awesome if this feature got implemented. maybe there would be a drop down menu that asks if you have a suffix or not.
i use this wether I'm based in the USA or Europe. for now I do it manually, and the way i do it - First Letter or number is my fleet code, middle characters are the sequential numbers, and the last two characters are my airline code. in MT8 I'm in Europe, so it goes D-AAME, D-ABME, and so on for one fleet, and the second fleet type it would be D-BAME, D-BBME, and so on. in the US, it is sort of the same, N101ME, N102ME, N201ME, N202ME, and so on.
sorry for over explaining, just wanted to be clear, that's all!
