Question @Recurse with context/prefix

[harscoet]

I have the following common options

case class CommonOptions(
    prod: Boolean = false,
    dry: Boolean = false,
    @Recurse slack: SlackOptions
)

with slack options defined with

case class SlackOptions(
    slackToken: Option[String],
    slackChannel: Option[String]
)

I would like to be able to define my case class like this

case class SlackOptions(
    token: Option[String],
    channel: Option[String]
)

But I want to keep context informations when I use command line

--slack-token=... --slack-channel=...

It should be great to have one annotation "@PrefixRecurse" (or similar) that uses the name used in parent in command line

--slack.token=... --slack.channel=...

Maybe do you have some tricks to do that? Using "ExtraName" is for the moment the best solution I found but I will have conflict If I have same keys in different context

case class SlackOptions(
    @ExtraName("slack-token")
    token: Option[String],
    @ExtraName("slack-channel")
    channel: Option[String]
)

It would be cool to have something like @Recurse("slack")
