Calendar App with Parent Child hierarchy

I am looking for a way to show the parent child relationship within our calendar. For our events, we want to show the event name (parent), then each task (child) so they are sorted and bundled together as they show in the sheet.

I am attaching how they show now. There is no way to tell other than the name, that they are related tasks. Is there a way to group them together with Parent task listed once and the the child tasks location underneath it?
