Code completion not intelligent enough?

In Pycharm if I import like "from pulumi_azure import core, network", the IDE finds the right libraries and offers code completion. If I use "import pulumi_azure as azure" and use azure.core.blabla() instead, the IDE can't find the libraries and doesn't offer completion.

A quick search led me to a page where it was mentioned that this is a bug, but the topic is from 2014.

I'm experiencing this frequently with Pycharm that it's not able to intelligently find all the libraries via _init_.py
