Ability to set hubs for custom/modded airlines

HUBS

I would like to see them implement the ability to allow modders to be able to set hubs for airlines. for example, if i download a mod of British airways, it would be great if flights into my airport operate by BA would come from London - However, if i decided to open my airport in London, flights would be to random places as it is currently in the game.

Why should this be a feature?

Well… it just adds a little more realism into the game.
