Worldbuilder at HotSeat-Games

Hello,
I often play HotSeat-Games against my friend. But we are not able to use the worldbuilder during this HotSeat-Games. Is it possible to activate the worldbuilder in HotSeat-Games?
And how can I use the CustomAssets-Files in HotSeat-Games?

Bye

I just overwrite original game files with custom ones, works fine... just make sure that you backup your original files.. might need them later

found temporary solution for map reveal in hotseat.. not a great one though...
