Highlight duplicate value in a column in Eloqua Insight Report

Summary:

Hello,

I have built an Eloqua insight report (Using subject area: Email Analysis by Send Date) and there's a column 'Order Number' which has duplicate values repeating for some entries. For Example Email address and Order Number are 2 columns in my report.

Email Address Order Number

test1@testing.com 1234

test2@testing.com 5678

test3@testing.com 1234

test4@testing.com 8999

Now, I want to highlight the duplicate value for Order Number or you can say repetitive value in my report (in this case: 1234). If this is possible, let me know how can I achieve this. It will help me to analyze my report more efficiently.
