Unit ground textures

Chrydgod used to have a WE enhancer type thing that allowed you to set a units splat to whatever you wanted, I was wondering whether anyone knows how to do that for 1.13.
I suppose I could import files under the paths of the normal textures, but then the downside would be that I wouldnt get the normal ground textures. Is there any other way?

I'll have a go at updating 1.13b's UnitMetaData.slk with Chrydgod's stuff, but I think they mostly do the same things.

All I need is the ability to change unit splats to whatever, if you could do that Ill'd be eternally gratefull. :D
If youve played Chrydgods old Cube D NE you can see what this allows you to do.
