It's interesting that you mention multivitamins. When I was burnt out I noticed that Vitamin B, D3 and zinc have a huge positive effect on my mood and energy level.
At the moment, there seems to be no way back. The page to convert an individual user account to an organization account (at https://hub.docker.com/settings/convert) explicitly states:

After a brief glimpse at the documentation, I am missing a feature comparable to Kafka's partitioning. Well, the protocol [1] briefly mentions it, but it does not seem to be exposed.
Getting insights into the roadmap for this would certainly be interesting...
