If you want to have a list like this in the free text editor:
1. aaaa
2. bbb
3. ccc
o ccc.111
o ccc.222
4. ddd
5. eee
6. fff
You have to follow these steps:
First start with the list without formatting:
aaaa
aaaa.1111
bbbb
Then you mark and number all of them (false) :
1. aaaa
2. aaaa.1111
3. bbbb
Then you indent the one(s) in the middle ( false) :
1. aaaa
1. aaaa.1111
2. bbbb
Then you change numbering to bullets (false) :
1. aaaa
o aaaa.1111
2. bbbb
The alternative is to edit first in a Word document and copy/paste from there.
