A cloud-based identity and access management service for securing user authentication and resource access
Azure does not have the same application group prioritization that Okta has so there isn't a priority for app roles, as Sam mentioned. If you would like to make a feature request for this feature you can do so on the newly revised Ideas forum. https://feedback.azure.com/
If you provide more details about your scenario I would be happy to bubble this up with the product team.
