Sure, so let's assume you have a notification set up today that works perfectly.
Create a date/time field called 'Send Notification' in the table where you have the notification working.
Create an automation. Set the automation trigger to exactly duplicate what you have currently in your notification trigger. Set the automation to perform two actions: 1. update [Send Notification] to the current date/time. 2. Write to a log or do whatever you want to do to track your notifications.**
Now change your notification trigger to fire whenever [Send Notification] is updated. Done.
** You could also just update the settings on that table to log changes to the [Send Notification] field, maybe. I think there's enough native logging capability now that that might be sufficient. I am never the one in my organization working with setting up logging so I am very shaky on details.
