Hi,
Thank you for the enhancement request. As you can see I have created a set of related issues in the corresponding components so you can track progress of it. Additionally I've created a request in RAML spec (raml-org/raml-spec#726) so it can be implemented in API Console as well (which is part of ARC).

Right now it is hard to tell when exactly it is going to be released but I will update the ticket once I have a plan for next release.
