Support for updating/adding chapter markers in Hybrid MP4 files

The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• Check out all the menus and keyboard shortcuts. Maybe the feature already exists?
• Try with the newest version from GitHub
• Read the documentation and FAQ, Known issues, Troubleshooting to see if the feature already exists
• See if someone already suggested this under Issues or Discussions

Description

I'm using Hybrid MP4 from OBS and I'm adding chapter markers live as I record. Sometimes in post I want to add a couple more chapter markers using LosslessCut, but I don't want to export to a new file, nor do I want to overwrite the existing file with a whole export; I just want to update the chapter markers in the Hybrid MP4 file. So what I want to do is just open the Hybrid MP4 file in LosslessCut, add some markers, and save. Can this be implemented?

Thank you!
