Ability to enable Global Mail Settings - Email puller on Sandbox

Currently, as mentioned here: Manage product sandboxes, when creating a Sandbox environment and performing Copy Data to production, by default, the Global Mail Settings - Email puller on Sandbox is set to disabled. The only when to enable this is contacting support, as it is disabled by a system flag.

It would be nice for Org Admins to have the ability to enable or disable it on Sandbox side.
