Automatically generate multiple landscape textures in CS?

[TheCountJames]

I recently made an island using GeoControl and successfully got it imported into Oblivion's CS. But I was wondering if there's any way to randomly and automatically add terrain textures from the landscape editor instead of painting it manually on the large scale map? What I mean is are there any third party apps or plugins that can do this or am I forced to just paint the textures manually?

 

One thing that annoys me about the CS is how there's no random brush button where you select from 5, 6, 7 different textures and it paints the ones you have selected randomly on right click.
