@cindy-peng any update on this? Is this on the roadmap or is there a different way to implement this?

[cindy-peng]

Sorry for the late reply @johnclara! I agree that adding CustomWriterIdentity parameter makes sense for the library. Unfortunately the team has been busy working on some other projects. I've added your request to our list and will let you know as soon as we have a plan in place.
