Multiple sub-model logic of COLMAP in GLOMAP

[is-jlehrer]

Hello,

I was wondering if there a source on the multiple sub-model logic for GLOMAP? I didn't see the multiple submodels as a CLI argument, and was wondering there is something fundamental about the global optimization scheme that makes sub-models more difficult or if it was not implemented yet? If not, no problem, I'd like to take a crack at it -- could you please point me to the COLMAP source code with this logic?

All the best
