sync command not setting correct content types

[vc-ash]

I used the b2 sync command to sync a folder from my server to B2, but the content types (file types) were not what they should've been. I am uploading .ts and .m3u8 files for HLS videos and need their content types to be set to "video/mp2t" and "application/vnd.apple.mpegurl" respectively. I can manually set them using the b2 upload-file command, but I have thousands upon thousands of files to upload and the sync command is much faster and more ideal to use.

I couldn't find any documentation for the sync command on setting the content types.
Are the content types (mime types) coming from what's defined in my system or are they automatically being set on B2's end when they are received?

Is there a way to make sure the content types are set correctly while using the sync command?

Thanks

Currently the mime type is based on file extension.

How would you like to set it in case of sync command?

It does seem like the current automatic content type assignment, which is done on server side using this list https://www.backblaze.com/docs/cloud-storage-b2-content-type-mappings does indeed not set the mime type automatically for .ts files (it does for m3u8).
