@SpyderBlack723 Not without manually editing the configs. Each subcategory needs to have a config entry.
Right, how would I go about that? I've edited the configs to change the name of the group categories (i.e. instead of just "Infantry" I've changed the group name to "Infantry (Rangers)", "Infantry (MARSOC)", "Special Forces (SF)" etc. etc.)
I just don't know how to go about editing the single units category name that it inherits from whatever soldier it was based from. I would like to change "Infantry" (the RHS USMC faction singular units category, comparable to NATO's "Men") to a similar set up as the group names, "Men (Rangers)", "Men (MARSOC), "Men (SF)", "Men (SEALs)", etc. etc.
I know I'd have to manually place the CfgVehicle classes under each subcategory, I just have no idea how to declare the subcategory in order to place the units under them.
