Supplying initial pose estimates

I'm having trouble figuring out how (if it is at all possible) I can supply an initial estimate for the camera pose. I'm dealing with a situation where the input images have very little overlap with one another but the camera poses are fairly well known. I wanna use OpenSFM to improve these initial pose estimates. I'm not super concerned with the reconstruction so long as I can recover better camera poses.

Is it possible to supply initial poses to the OpenSFM command line scripts (and also tell it that the estimates are "high quality")? If not, can someone suggest which part of the codebase I should be trolling to get the functionality I need? Thank you :)

Start by tracing the OpenSfM command-line scripts and the camera-pose handling relevant to supplying initial estimates. Determine whether initial poses and a high-quality setting are currently supported; done would be a decided implementation or a clear answer identifying the code area and required scope.
