Multiple Terrains, Is there a way to use the same texture, tree and grass objects without having to set them up for each terrain

As it stands you have to create terrain textures, add trees and grass objects for each terrain you work on. But if I'm using multiple terrains, i ideally only want to set this up once, rather than have to go through the same process for each terrain I'm working on.

If there are any assets or any way around this I would be much appreciated.

EDIT

Ok I've found Terrain composer on the asset store which solves my problems!
