[SOLVED] Need some help with my first server

[Machlath 0]

So i just setup my first Arma 3 server for combat patrol. I only wanna play combat patrol with official missions on it, i managed to setup the map rotation but i wish to change the mission parameters (like objective or daytime) but i don’t know how since i only play official maps. It works ingame as an admin but I’d like to have the settings permanent. I know you have to create a file for edited/created maps and add the „class params“ lines in there but that won’t work in my case. Adding the lines to the .cfg does also not work.
 

Is that even possible? If so please tell me how.
