SageX3 - Left List Personalization

Hi, how can I add custom  view fields into standard (browser) object Left List ?

It's easy to add other tables but , what about views ?

Example:this is a standard object 

I've added my custom view into Viste tab:

But in Selezione tab (Selection) I'm not able to add any view fields...

Anyone knows how to solve this 'problem' ? 

Thanks a lot!!
