Need is to have a task which is the summary of a bunch of other tasks.
Ideal would be to have "sub-tasks" automatically handled, but also having a single task starting when first of "bunch" starts and ending when last of "bunch" ends would be acceptable.
I tried somethong along the lines:
@startgantt
-- Connect.ME --
[AG550Q/AG215S connected to sb001] as [CMa] lasts 3 weeks
[BT integration] starts at [CMa]'s start
[BT integration] lasts 3 weeks
[CMa] ends at [BT integration]'s end
[Commsignia integration] starts at [CMa]'s start
[Commsignia integration] lasts 1 week
[CMa] ends at [Commsignia integration]'s end
[Control.IT integration] starts at [CMa]'s start
[Control.IT integration] lasts 2 weeks
[CMa] ends at [Control.IT integration]'s end
@endgantt
... but it doesn't seem to work as expected.
