MediaLive HLS Segment Separator

Hello All,

I am trying to match an existing workflow for a migration to Media Live. My current setup produces a ts segment with the syntax ..../file-00001.ts etc

MediaLive produces segments in the format of ..../file_00001.ts etc

In the documentation from AWS it clearly shows the syntax I am looking for but at some point has been changed without updating the documentation.
See Link below
https://docs.aws.amazon.com/medialive/latest/ug/hls-custom-paths-examples.html

Does anyone know of a way through settings or API workflow that would change this segment separator?

Thanks,
Jay
