I am creating flowcharts within InDesign as it seems to work better for me than in Illustrator. The Layers Panel allows me to do this. But I really, really wish I didn't have to do this workaround. These are my personal notes for future reference:
Grouping for complex assemblages of objects: creating a new group
This is needed because the Layers Panel won't allow you to group items deep in the Layers Panel, only if they're at the top level; you can't create a "Group within a Group."
- Use Layers Panel
- Keep two objects (doesn't matter what) off the page named "Dummy Object," select them with the mouse, then Menu > Object > Group
- Rename this to what you want your group's name to be
- Drag TWO OR MORE objects or groups into this group
- Drag the two Dummy Objects to the top of the Layers panel
to get them out of the group
- Drag the new group to the right position in the Layers panel
