CK - Faster way to spawn trees?

[GomuGomu64]

I'll make it nice and short:

 

Is there a function in the CK that allows for quick-generation of trees? Click-drag-ing gets very tedious on large landmasses, copy-pasting premade forests requires a lot of repositioning, which, is also, tedious.

 

Is there any function that will generate trees on the terrain without having to be repositioned?

 

Thanks in advance.
