CMS Federation for resisted local access?

I’m just dipping my toes into Webflow and have been going through the University. I’m working on a larger enterprise site that is looking to have its local branch office’s have restricted access to editing their local page with relevant events and topics. IE, they have a ‘local & recent events’ section that each local branch is able to update and curate. We don’t want to give each branch full access to our Webflow document.

I’m reading more about the CMS API, which maybe the solution I’m looking for here (combined with some code or perhaps zaps depending on what the powers that be decided? ), but I wanted to see if there were any out of the box solutions that I was missing or if anyone more versed in Webflow has solved this problem.
