[Help] One panel for multiple area

Hello, 

I am not sure how to do this but I wanted to have only one ckeditor panel on my page and not on panel by area to edit.

So is it possible to link a panel to multiple editable zone or do I have to deal with one editor by editable zone ? 

Bytheway, it will also solve another thing with the inline editor floating panel, I wanted to fix it in a specific selector.

Hop this is clear, and thanks you for any answer.
