List Showing The Results In Aggregate

Greetings friends PHPRunner
Just as there is the possibility of grouping the results of a report, I wondered how it could be made to group the results list. If it is not possible at present, it could be considered in the next version of PHPRunner.
Why does this need?

Generally working with lists of master-detail, then in that scheme I have the need for a detail display listing results grouped by a particular field, as shown in a report.
Is it possible to bind as part of the schema master-detail, list a linked report, so the report is the detail?
Awaiting your kind response to this.
Sincerely.
Pasquito
