Unity Terrain Wind Settings for individual types of grass textures?

This might be a bit difficult to explain but what I am trying to do is use Unity's Terrain grass system to create regular grass (affected by wind as usual) and "grass textures" that are not affected by wind (in this case patches of pumpkins)

Both the regular grass and pumpkins are 2D images. Is there a way to have wind affect the grass but not the pumpkins?
