Dual sound recording on 5DIII

[teamDOMINO]

Hi guys!
First of all sorry for my english - I'm from Ukraine 

I've just install ML on my 5DIII 1.1.3. and can't find where can I turn on external and internal sound record on it?
This option is my favorite on my 60D with ML2.3. 
What I need to do to enable it?

Thanks
