How to promote/demote Excel rows to new outline group level?

G

GY2

I have a 50 row outline grouped into 4 levels. I'd like to know how to make
the following two modifications without having to ungroup and regroup the
whole outline every time.

1.) I would like to insert new rows to create a new group at, say, the 2nd
level.

2.) I would like to be able to promote/demote existing rows.

All advice will be appreciated.
