Force focus on editor handle

I'm creating a level editor, and through a custom editor script I can click to place instances of my game objects, at which point I force the Selection focus. After I bring focus to the object I have to click my FreeMoveHandle to start moving the object.

Is there a way to force the editor to focus on this FreeMoveHandle immediately once I've brought focus to the object? So placing objects and beginning to move them can happen in one click+hold, rather than the selection box that happens with a non focused click+hold.
