VLC 2.x series: Sout - Transcode string missed in convert/save panel

In vlc 0.8.x You can read and edit ( if I like ) the sout trascode string

In the stream output interface panel You have:
------------------------
Stream output MRL

Target: :sout=#trascode{vcodec= ......
-------------------------


I'd like to know how to setup (if possible ...) the VLC 2.x interface to access ( read and edit)
the sout trancode string in the convert/save panel.
By clicking the Edit button (represented by an icon of a screwdriver and wrench) to the right of the drop-down box
I can choice 'incapsulation, video codec, audio codec, subtitle' but I DONT HAVE and than I cannot read or edit the
sout - transcode string


Thanks in advance to all of You
