Proposal - a setting in the Livery Designer menu which could set a custom livery as the 'default', so instead of just a few random trains using the custom livery all trains would use it. This would, for the most part, remove the headaches of trying to import/export liveries using 3rd party mods and the PC editor for players with limited knowledge in terms of game development, such as myself.
Just thought of a way this could be implemented - another option on the AI usage options in the livery details menu
