Two Suggestions:
- Have you checked the grass available in Quixel Megascans ? Possibly with some rotation when placing the asset could give you a similar appearance to the blown over look.
- Another option would be to import your Twinmotion project into Unreal Engine. There you can paint the grass whereas I think you still must place Megascans assets individually in TM. UE allows adjusting a lot more in the placement for different looks also.
