Numbered title (h1, h2, ...)

Hi,

I wanted to know if it's possible in CKEditor to have numbered title as we can have in Word for example :

1. My first Title first degree (corresponding h1)

1.1 My first title second degree (h2)
bla bla bla

1.2 My second Title second degree
Bla bla bla

2. My second Title first degree

etc...

I don't find anything which could allow it and no plugin too. Is there one ?

Thanks a lot
Bastien
