How do I merge actors in 4.12?

In older versions it was an experimental function, but according to this it has been released:

The problem is is that they don’t tell you where you can find the merging menu.

So my question is, where can I find it?

  • Open Unreal Engine 4.12
  • Select Window menu
  • Go down to Developer Tools
  • Under Miscellaneous, you’ll see Merge Actors

Thank You!
