How to save/retrieve new data structures into save game

[ZheBerg]

Hello,

I would like to create a fleet structure that would help me handle attack group AI.
Is there a way to save a basic structure, let say, fleet id, fleet role, fleet current objective and list of unit coordinate and unit role ?
Or will I have to launch a script a the loading of a saved game to rebuild those structure as best as I can ?

Thanks
