Can you create an ArtifactRef from an artifact ID in DNG Client Extension API?

I've been looking into the DOORS Next Gen JavaScript Client Extension API and was surprised by the limited number of ways you can get an ArtifactRef to perform operations on. The documentation (for 6.0.6.1) basically says that ArtifactRef is a black box and you shouldn't try to construct or modify them outside of the extant API, but is there (or will there be) a way to construct them from a given artifact ID? The tool we're working on is given information to create a new artifact and the ID of an existing artifact to link it to, but we can't get a reference to that other artifact to make the link. Does anyone know how this could be done without recursively searching the modules and scanning all artifacts for the one with the proper identifier?
