Moving a spline point along its right vector?

Hey folks, I’m working on some editor widgets to aid in workflow and can’t quite figure part of it out.

What I want to do is offset each point in a given spline to its right by a certain amount. In the viewport, toggling the translation gizmo to local allows me to move spline points along their local Y axis, but I can’t seem to replicate this behavior in blueprint. You can specify a local coordinate space in the “set location at spline point” node, but this seems to be local to the actor as a whole, and not individual points.

Any ideas? Thanks!
