You are right! We designed phoenix3 for exaclty this use case!
Unfortunately, all that is undocumented at the moment, but what you
should be doable quite easily.
Right now, the only advice i can give is to have a look at all the
modules that are implemented.
I will reply the minute the docs are finished ... in the mean time i would
be happy to help finding a solution to your problem.
