I cannot find a way of navigating from the report to underlying source (apart from sheet name column, which messes up with the presentation - so I typically remove the column form the view).
Plus, having the sheet name on each row is annoying. So in few other instances, I grouped a multi-sheet report by sheet name. The sheet name in the sheet name column is a link but sheet name as listed in the group header is not - bummer.
The only workaround I found so far is to go to row properties and click on the row link which would lead to the source sheet, from which I can navigate to other rows I need to use. Clunky.
It would be ideal to have a tool bar or side / feature bar icon to navigation to selected source sheet (to prompt for selecting a source for multi-source sheet or go directly for single source one).
