The current ticket report is ok but has limitations related to tracker tickets.
1 tracker ticket is linked to multiple conversations. It would be great to see in the reports how many conversations have been linked to tracker tickets over a given period. This gives a more accurate impact of the issues related to tracker tickets.
For example, if there were 5 tracker tickets last month, there can be a big difference in impact if only a handful of conversations were linked to the tracker, versus if 20 or 30 conversations were linked to each ticket. It would be good to be able to see this in the reports.
Alternatively, having a way to automatically tag a conversation when it is linked to a ticket would help generating custom reports for this.
