Short answer: yes starting from next release
Long answer: in a couple days in ArviZ development version. We recently added capabilities to ease this in ArviZ, mainly with InferenceData.extend for which I have been working on a tutorial blogpost to be published this week. While writing the post I realized there was a bug in extend which will be fixed by this already open PR.
Glad to be of help! I actually was not sure it would work given that there must be an error of some kind for docs to not be properly generated.
