Insta360 Studio 2020 - Export to .insv

Is there any way to export a clip from an .insv file to another .insv file (rather than as an mp4)?

My phone isn't capable of loading the size of files that I take on my Inst360 One R, and I'd like to continue to shoot long videos and then extract clips that I can process using the tools that are in the app but missing from Studio (such as the Stories).

If I could load the 30GB+ files onto my PC, but then export small clips to process on my phone, it would get around the missing features from Studio.
