Interface Utilisation Business Hour Query

Hi,

I am trying to create a business hour report for critical Wan links utilization in each site. I was able to tag them using interface custom property "Reporting - Wan Links". Below is the screenshot of the requirement. I am able to configure the same except for the 2 highlighted. We would like to see how much time an interface exceeded 80% utilization in a week between 9 to 5 hours.

Can we do this in a Web-based Report Writer?
