[Typo3] [TemplaVoila]How to customize position of CE box in backend ?

[Francesco di Francia]

In my homepage template i have 4/5 different Areas. This Areas are EL 
type, content element type.
In the backend i see all these "boxes" in the same row.
There's a way to modify position of the content element boxes in the 
backend ? ( i.e. 2 up and 2 down )

Regards,

Francesco
