Does any AI editor do this?

Hi,Long time reader, first time poster.I've been looking for an AI program that will allow me to specify the routes I want an airline to fly and the fleet size, then it takes over and does the scheduling.From what I've been able to find, programs won't let you create a schedule using point A as a main base, with flights to point B, C via B, D, etc. They will let you just use A, B, C and D, but won't schedule so that every flight either arrives or departs from just point A.The closest I've seen is My Traffic's use of hubs, but it's a laborious process to create a hub at A and then block every airport out except B, C and D.Any thoughts? I know my way around AI editing, but in all my travels haven't discovered what for me would be the 'ultimate' tool.Cheers.
