Supplying commit hash via dockerised Nexus IQ CLI

Is there a way or plan to support supplying a commit hash in the docker version of the Nexus IQ CLI?

Looking at the instructions here - it mentions a --metadata flag:

https://help.sonatype.com/integrations/nexus-iq-for-scm/ci-and-cli-integrations#CIandCLIIntegrations-InstructionsforUse

However (as also mentioned in that same documentation) we are using the dockerised CLI for this:

https://hub.docker.com/r/sonatype/nexus-iq-cli

But this seems to have different usage and doesn’t mention the metadata or commit hash. Looking at the image, it is running a docker specific jar file:

java -cp ${SONATYPE_LIB}/docker-nexus-iq-cli.jar ${SONATYPE_IQ_CLI_PKG}.NexusPolicyEvaluator
