Hello,

There are records that naturally have no joins to each other (Activity.Calls to Employee) for instance. More examples can be found when looking (and not finding) related records in say a specific saved search.

To overcome this limitation, my idea would be to create an intermediate record (called Statistics or something like that) and then manually create the joins needed from specific fields from the call.activity record. Then, a field could be created on the employee record that accesses the statistic record field to get that field data. Essentially the Statistics record is merely a 'bridge' to get data. It would look a bit like this.
