How to keep compliant imagery seperate by market?

Hey hey, just got a mid-size MSO client operating across six states and one of the first things we discovered is their brand asset situation has become a compliance risk.

Their dispensary partners and regional marketing teams are pulling from a shared Dropbox folder so no way to gurantee the right state approved imagery is being used in right market.

Also, their last quarter had a retail partner running point of sale materials with packing photos that aren't approved in their state.

Looking for way to give each regional team self serve access to only the assets cleared for their market like logos, product imager, compliant copy etc without them grabbing something from a different state's folder by accident.
