You can link a linked policy template with multiple tenants, which allows you to make a change to the linked policy and update all of the tenants that you have linked with the policy simultaneously.

For a non-default linked template, when the linking request creates a new policy in all tenants selected for linking, an email message with linking status details is sent to the administrator. For a default linked template, when the linking operation updates the default policy in all tenants selected for linking, an email message with linking status details is sent to the administrator.
