This report has some options, but no date. A date field would enable data to be dumped for TPs that had exchanged data since date xx/yy/zz. Thus you might say show me the customers who exchanged data in the last 3 months (who might thus reasonably be considered as live customers).
The full report can be lengthy and it is not simple to sort on the date field for an exported report in Excel. The date restriction needs to be enabled in the InFlight reporting function.
