Custom Spline Leaders Via Adaptive Components?

[r.grandmaison]

I love Revit for so much...but am a bit dismayed in its lack of ability to do some things with annotative objects the way AutoCAD can. I love the way AutoCAD handles Mleaders as splines with the ability to create and use custom arrowheads and multiple control points on the leader splines. I really wish Revit had similar abilities.

So, has anyone ever created a custom leader that could mimic the spline leader in AutoCAD even if it's done as an adaptive model component that must be suppressed in non-model views? I want these things:
1. The ability to have at least three control points with bezier type fuctionality.
2. The ability to create a custom arrowhead to my own liking.

Any luck with this one?

I would like to place a spline leader to indicate where I am relocating items to / from. I can do a work around by creating a spline and then placing the symbol of an arrow head on it but I would rather they were connected as one.

There is now the ability to make multiple leaders, as arcs, with control points, which in my opinion, is good enough.
