GameUserSettings.ini queston

Hi i look for a config for the graph with true ore false.
I like to give the mod users the option to disable or enable the cross hair from the weapon in the mod. Can every body say me
what must do in the graph for this option? I know in the weapon blueprint is the option for the crosshair.

What your asking for is server sided. Not client sided options. Assuming i read this right.

i like to make this cofig only for that weapon, that other weapons can have a crosshair only that weapon will be a single config to disable or enable it. It must work on server and client side.
