Can I pass a value into Conflict() ?

In my scenario I need to return "Retry-After" value when the result is Conflict (basically a `DateTimeOffset`). Is this possible?
I looked into the code and the only way to pass anything is `errorMessages` array.

I think this is a valid scenario.

Start at the Conflict() entry point and its errorMessages argument, then review the existing result-to-HTTP mapping described by the repository. Define and verify support for carrying a DateTimeOffset Retry-After value with a Conflict result; the issue names no file or test, so the appropriate implementation point and acceptance coverage still need to be identified.
