Yes you are right I have auto generate disabled so it's loading in the frozen BB tracks only and the Utility RealCharts.
If you can get that sorted it will be good so users will get the same tracks they worked on in Biab.
After opening the SGU if I select Import the same SGU it will import the same frozen BB track sections to new tracks, so that's good to be able to import another frozen SGU to the same project if you want more than 24 tracks.
