Quote: "So the question is: is it possible to see a log for the objects being lightmapped so problematic objects can be dealt with?"
Problematic? Those long lightmaps aren't problematic, they're just complex.
Lightmapping only takes a significant amount of time during the testing and building process. When you build your game into an .exe file, the lightmaps are already calculated upon loading, so loading the levels takes very little time compared to when you test it in FPSC.
The long lightmapping times you experience are simply an inconvenience to you because they are so complex. Try altering the setup.ini file to have a lower lightmapping quality for testing, then increase it when you want to do final checks and adjustments to light quality, and for building the final executable.
