Hi All!! I’m struggling a bit with some custom event reporting and hoping to lean on the experts here for some help!

We are collecting a custom event for a backend job that processes a number of records, and we are collecting a number of relevant properties along with that custom event: StartTIme, FinishTime, CountOfRecords, and DataSize. I am trying to find a way to extrapolate total job runtime (ie, FinishTime - StartTime), and ideally tie that to either number of records or total data size. Unfortunately, the only way that I know to capture or view specific property values is through the Query Builder which, as far as I’m aware, will only let me view one property value per custom event occurrence. 

Is there a way for me to either A) display multiple custom event properties in the query builder table (or in another report in PX!), or , run a report to do that FinishTime - StartTime calculation for me? Thank you so much!!!
