Hi Tyson,

unfortunately there's no way to do that currently. The fact that it
partly works now is actually a side-effect of the SoC project on
cross-package documentation. I don't think much more work is needed to
complete this feature, but no one is working on it at the moment. If
you feel like doing a little bit of hacking it could be a fun project!
