Show individual child items in Gantt view when the parent item is collapsed

We often need to report our project timetable for the client, but TeamHood pdf-exports are almost useless for this purpose.

One huge improvement would be if the child items could be presented separately in Gantt view when the parent item is collapsed (see the picture). Child item "dots" could have item names hanging above them (ie. "Meeting 1").

We cannot send forward timetables where every item is expanded, because then the readability of timetable suffers a lot. Rows should fit to one A3 (pdf) page when exported.
