Enhancement Idea

First of all—you are AMAZING for making this awesome tool! Now for an idea:

I am not a math genius, so I have no idea if this is possible. But I'm trying to match a scene that has few right angles. However it does contain a perfectly round plate.

Is it possible to calculate the perspective from an ellipse that relates to a real-world circle? Or a combination—say if we have one tabletop running through the scene providing one straight edge, and a circular clock on a wall providing the chance to match an ellipse?

Anyway, it's awesome as-is. Thank you!
