Device grouping and admin rights delegation

We own multiple properties all of which currently have multiple Nuki devices. Several of these properties are offices which have a large number of users. We want to be able to delegate the user management for all the Nuki devices by property. For example, “Office A” may have 2 Nuki Smart Locks and 30 users and “Office B” may have 1 Nuki Smart Lock and 5 users. Each Office has a manager who we would like to make responsible for user management for that office and therefore for all Nuki devices installed at that property. At the same time, such a user should not be able to see or access any other devices than those belonging to the property of which that user is the manager. It turns out that this is not possible with Nuki web! So after many years of using Nuki devices and managing everything myself, we are seriously considering switching to a competitor product which supports proper admin delegation and segmentation by property. Am I overlooking something?
