Hi Juan,
There aren’t any plans at the moment. We’d like to eventually add hit testing for splines, and if that happens, we’d almost certainly add a key to be able to insert a reroute node directly on the spline you clicked.
However, for right now you can add something like this to your DefaultEditorUserSettings.ini in your game project:
In DefaultEditorUserSettings.ini:
[BlueprintSpawnNodes]
+Node=(Class=K2Node_Knot Key=R Shift=true Ctrl=false Alt=false)
Which will cause it to insert a reroute node when you click the mouse while R is held down, but it won’t be wired up to anything.
Cheers,
Michael Noland
