Timesheet view - non-template slip list

This feels like a very stupid question so please bear with me.

Customer is using the Timesheet view in Timeslips. Templates all set up. As we know, if someone creates a slip in the traditional way and it doesn't match the details of a template then the time will go into non-template time on the timesheet.

How do I create a list of slips that are in the  non-template total? Preferably in the slip list so we can edit them to match a template or create a template to fit - but a report may work as well.
