Exisitng or New Container needed ?





I'm trying to change some parts of the default skin and hit a dead end.


I'd like have a panel of Posters (so  type="panel"> ) but focused item should have fixed position. 

  type="fixedlist"> comes close to what i'd like to accomplish but it only offers one column/row.


I checked XBMC Wiki but I didnt find any container that fits the bill. Are there any known workaround how to accomplish this ?
