Can't Trim videos on desktop app??? seriously?

I cannot believe that a function as simple as trimming is not included in the Insta studio desktop application.... seriously?

I edit all of my footage in Premiere Pro. In order to do this I have 1 of 2 options without the ability to trim video within the Insta studio desktop application.

Option 1: Trim footage on Insta 360 phone app

Problem 1: Constantly losing connection between phone and camera making trimming multiple clips an all day affair

Problem 2: Insanely slow playback or non existant making timming impossible unless downloading all footage to phone (unrealisitc option)

Option 2: Uploading full length video files to computer, and trim in premiere pro

Problem 1: Full length 5.7k video files are so large that playback or rendering within premeire pro, as well as the creation of proxy files is impossible without a seriously powerful computer.

This lack of desktop function makes owning a Insta 360 One R useless for editing film other than for simple Social media posts.

I would be so grateful to hear if anyone has found a solution for desktop editing footage.

Thank you.
