Using LandscapeGrassOutput how can I stop foliage from aligning to normals?

I have a simple LandscapeGrassOutput built in my landscape material, but when the trees auto generate they slightly tilt, I would like them to just go straight up, any suggestions on how to do that using GrassTypes and the LandscapeGrassOutput ?

If I uncheck Align to Surfaces in the GrassType, they go straight but they do not connect with the ground nicely there is a slight gap from the trunk and the floor
