Split forum into two "divisions"

I have a discourse forum for support and knowledgebase for a particular set of customers. Changes in my company mean that there will now be a second set of customers that would require a similar forum/knowledgebase, but I want to keep them separate from the first. Is there a way to split the forum into “divisons” so to speak that I can still administer overall, but users only have access to one or the other etc.

A little while back I wrote this plugin that would bring each set of users to a ‘home’ category when opening the forum:


If someone has a primary group registered and that is permissioned to a single category, it redirects to that category as home.

I don’t pro-actively support it, but it proves the concept is workable.
