Share articles across multiple brand accounts

We handle a few different brands via Zendesk through different Zendesk accounts. The product/service offered by the different brands is the exact same. Due to the similarities, we often have same exact articles/FAQs across the different brands with only the brand names changed. 

Currently, this requires us to create separate articles and keep them updated separately. As a step 1 improvement, it would be very convenient to have the ability to share articles across our Zendesk accounts.

2: Updating article in one account (main hub) and having the ability to sync the changes across other Zendesk accounts would also be helpful. 

3: Being able to identify the "brand name" within the article and dynamically change the brand name when an article is posted across different Zendesk accounts.
