Some questions regarding modding civs (Genie Editor)

I've been fooling around with the Genie Editor for a while, but there's some little things I haven't wrapped my head around yet. First thing would be how to show unique non-castle units in the tech tree (moved around the Imperial camel), any idea how to move that to a different civ? Secondly, I managed to disable Stone Walls/Gates, but it doesn't show in the tech tree (like with Goths or Cumans). And lastly I'd want to play around with the Khmer farming bonus, but I can't seem to find it anywhere, anyone any ideas where that could be hidden?

Also, although not as important, would there be any way to modify certain aspects of the architecture styles, as in, having a civ with Asian Architecture, but Central Asian sails, only regarding that civ specifically?

I'd be thankful if anyone could answer some of these questions, even if that includes a different program, no issues with that ;)

Also first ever reddit post, so yay i guess
