Save foliage actor

Hi,

I’m painting some foliage mesh onto my terrain and I would like to save it to use it in multiple maps.
I can’t even see the foliage actor in the World Outliner (only see it in the details window when I select it in the world)
Can it be saved out to use later (I tried convert to mesh but that just saves one instance of the mesh used in the foliage)

Thanks
