ID Number automatically added to URL: How?

I’ve a problem, and maybe you can help me:
In my two joomla site  i use sef advance and to add the univoque ID NUMBER to the url of each article I’ve to save the article before the pubblication, than delete the alias automatically generated, 0-ipad-air-apple-raccoglie-un-altro-successo.php and save again and pubblish; at this point i've an url like this http://www.****.it/16720-ipad-air-apple-raccoglie-un-altro-successo.php

On the other site, i've to add manually the id number to the alias !

Is it possible to let the sef advance add it automatically for me ?

I need it because google news indicize just url with an univoque id number.

SEF Advance has this feature: Append unique ID
Set that to Yes and that will solve the problem with Google News.

Hi, i've activated that feature but the id is Not added to the alias, i can see the id created but the alias is clean...

No news? I can't add automatically ID to my alias ...
there's a way to do this with SEF ?

A unique ID is added to URLs. That makes URLs accepted by Google News. Why does it matter it's not added to alias record?

because i've not an id added to the url ...

this is what i see when i create an article

Id is not in the URL ...
