SLA for Queue item

Hi All,

I have a requirement for one of my client where a email has been configured for a queue.

Whenever emails comes to that email Id, those mails are getting diverted to one of Queue in D365.

Now my clients wants to create a SLA where if the email is in the same queue for more than 24 Hrs, wants to notify Queue owner.

I checked that for Queue and Queue items SLA cant be configured , is there any other ways to meet this requirement?

Thanks

Alok
