[texhax] koma-script & date

[v.demartino2 at virgilio.it]

I'm trying to make koma-script  scrlttr2 class "speak" Italian. 
Now I've found that the folllowing options produce a well structured and
formatted Italian letter :

\documentclass[fontsize=12pt,% 
paper=a4,%
SN,%
enlargefirstpage,%
pagenumber=botcenter,%
parskip=half,%
fromalign=left,%
backaddress=false,%
fromemail=true,%
subject=beforeopening,%
fromlogo=true,%
italian]{scrlttr2} 
..................................
\setkomavar{date}{Roma, \today}
.................................

with the only exception of the  ** date ** which is placed to the right
between the recipient address and the subject while, according to Italian
standards, it should be placed to the right well above the recipient's address
and just below  of the right top header.

How can I modify the position of the date in the koma-bundle?

Ciao
Vittorio
