importing pre-solved cameras into syntheyes to add points

[Neilg]

We're working on a job with pre-solved cameras, but no tracking points in the scene and a need to re-build a fair bit of the geometry.
Is there any way to import my camera from max into syntheyes, run a tracker over the footage from the 3d camera and export the point cloud?

I've been scouring the help for ages but I cant figure out if it's possible... seems like it should be :/
