Scattered Interpolation: Defining my own triangulation?

I'm interpolating data the comes from polar coordiate systems or terrain-following coordiante system used in numerical weather models. While that data isn't gridded in the since that it's not grid aligned, it is structured.
Scattered interpolation is slow. My understanding is that this stems from computing the delaunay triangulation. For my data it would be trivial to provide the triangulation connectivity graph along with the points.
Is there a way I can provide a pre computed triangulation to scatteredInterpolant or griddata in order to speed up my scattered interpolations? Is there some hidden class property I could fill in somewhere?

Hey Matt,
Did you manage to find a solution to this? This idea has recently become relevant in my own work, and I would be grateful if you were able to share an successes you've had.
Cheers,
John
