auto X-mirror for splines (bezier curves)

To whomever added auto X-mirroring to Rigging & Posing, thank you so much!! You have sped up and improved my work immensely.

Please consider adding similar functionality to Bezier curves used for Spline-IK . Please let me select 2 curves with names ending .L/.R and edit them with mirroring.

I use many of these in rigging. With auto-X-mirroring, I can modify my rigs and easily maintain x-symmetry. This currently breaks when I get to the rig-splines. Currently the best option is to modify one spline to reflect the new bone locations, update/recenter the hook modifiers, then delete, duplicate, mirror, rebuild hook modifiers... etc. It's tedious and error prone.

Thank you for blender!!
