Per-material-instance LandscapeGrassType?

I have made a landscape material and added a grass node to output grass coverage. The type of grass (the LandscapeGrassType) is attached to the grass output node.

However, this node is per material, not per material instance, and I can find no way to make it an instance property. That means if I want to use the same landscape material on a different landscape, it has to share the same grass.

I’d really like it to be a material-instance level property! I want to make this an official suggestion to Epic, but before doing that, I wanted to double check that I’m not just missing the way to go about it. I’ve only just started to experiment with the landscape system so didn’t want to raise a suggestion to Epic where I missed a way to do it due to being a clueless noob :stuck_out_tongue:
