Is there a way to "paint" rocks on a terrain?

Hello people.

I'm working on a school project where we are developing a game in Unity.
We are currently working on our terrain, and we have several rocks that we want to place around the map. We tried using the tree-placing method, but it doesn't work - When we paint with rocks in stead of trees, nothing happens, neither in the scene view or when we play the scene.

Are we doing something wrong, or is it simply not possible to do it this way? And is there another/better way to do it?

Thanks!

I haven't done it in a while, but I've "painted" rocks using the built in terrain editor for unity. I don't remember the exact method, but it should work. Just play with it a bit more.
