Adding MDC parameter as additional-field in quarkus json log

[angelfrend]

I am using io.quarkus:quarkus-logging-json in my quarkus app. The document says that to add additional field in json, I should use below property,

quarkus.log.console.json.additional-field."field-name".value=

How to use MDC.get(paramName) as the value for this additional field ?

I don't think there's a way to do it, but would be great if the following work:
quarkus.log.console.json.additional-field."test".value=%X{mdc-value}
