Editing BP spline in viewport

Hi, I’m trying to use a BP for instancing meshes along a spline in the viewport editor. My problem is that I can’t edit the spline in the viewport, only in Edit BP, which lacks all the visual cues needed. How do I set the BP’s spline to be editable in the viewport. I’ve read about “Allow Spline Edit per Instance” but can’t find it anywhere in the viewport or the blueprint! Help me Obiwan… You’re my only hope.

Duh. I had to press G.
