I can actually manipulate the svg directly in Inkscape, changing fill and stroke, and the Z-order. It just behaves a little funky so is a bit non-intuitive and needs a little trial and error to get the right effect.
If you saw how many levels my model already has, you would probably start backing away from the crazy person, not tell me to create more! ~53 spread over 4 rows at the moment. Yes, I have an addiction problem - tabs.
Oh to have a unified Collections/Objects tree like in Blender...
