Workshop Attendance within Date Range

I note that there are two attendance reports which display attendance in percentages:

• Intake Enrolment Attendance within Date Range
• Unit Enrolment Attendance within Date Range

Is it possible to create a report which would also do the same for Workshop Attendance, ie create a report Workshop Attendance within Date Range and display the attendance in percentages rather than hours. 

I am aware that a learner is booked into a Workshop rather than Enroled.  

Cheers
