Using 3D Camera Tracker to Track a Long Shot in Sections

Hello Adobe community!

I've used After Effects for many years but haven't used it for tracking very much.

I have a rather challenging shot to track and I'm finding that the 3D Camera Tracker is analysing the shot ok but just hangs at the solving stage. The shot is a bit of a beast, being mono 360@60fps and around 5K resolution. That works out at around 9000 frames. I'm using a dual core Xeon E5-2630 with 128GB RAM and a 12GB TITAN X and am running After Effects CC 2018 (15.1.2). I am also using the Immersive Video tools workflow to track as advised in multiple places for tracking 360 video.

I ran a test where I was able to track a 500 frame section of the video, so my question is; is there a way to track a long shot in sections with 3D Camera Tracker and then piece the sections together?

Thanks in advance for any advice!
