Change color map for each plot in a 3D graph

[Jacobier]

I put a line and a parametric surface into a single Graph, and use property node to change the color map (This can't be done in front panel. I don't know how.) The problem is property node only point to a single plot and there is no way to assign individual color map to each plot. Is there anyway I can overcome it?
