Feature task group in Gantt (black line) :)

I am PM with high experience and I found that gantt can be used but problem is that there is no group task. It critical to show large project structure and organize small task into groups.

@startgantt
[Task 1] lasts 10 days
[Task 2] lasts 15 days
[Task 3] lasts 5 days

[Group] starts at [Task 1]'s start
[Group] starts at [Task 2]'s start
[Group] starts at [Task 3]'s start
[Group] ends at [Task 1]'s end
[Group] ends at [Task 2]'s end
[Group] ends at [Task 3]'s end
@endgantt

This is example how it looks like (groups can group tasks but also groups).

I have a gantt chart where this would be really helpful. It would need a keyword that also allows showing/hiding all the subtasks in my opinion.
