Setting the time of the Daily Digest Notification

I have email notification set in M-Files Desktop to send "A digest message once per day."  With this rule, I receive an email on the following day for new files created for the current day.

I receive the email notification at 8AM daily.  

If I create documents today,  I would like to send the notification at the end of today at 5PM, and not tomorrow morning.

When I go to the admin area:  Advanced Vault Settings>Notifications.  I have two options:  Build in Rules and Push Notifications.  These do not have anything I can set that would change the time and day of notification.

Where do I set the time and day of the notification?
