I'm wondfering if anyone here can help me, I'm loving this game but having a bit of a problem in the campaigns where im ruinning just short on time.

I know you can change the endgame countdown timer by editing something in the game rules but i was wondering if anyone has created a mod already to change or remove the timer?
I have looked through the mods in the workshop but can not find what i need. I was wondering if anyone knows of a current mod or a project underway which will help?
