I was going to cobble up a quick script to turn rows starting with tabs into child rows, but I see upon constructing my test case that OO already handles it!
Code:
This is a row
This is a child row
This is another child row
This is a top-level row
This is another top-level row
This is a child row #1
This is a child of a child row
This is a child row #2
This is a final top-level row
when selected, copied and pasted as described above yields
