Permalink & Structure

Hello, sorry for my english i use a translator…

i have a site in other cms and now i would migrate to wordpress 3. Now i testing WP (i install in subdiretory) and i have a question.

My structure in current (not WP) site is:

– Category News
– Subcategory A (ex. PS3)
– Subcategory B (ex. PS2)
– Category Review
– Subcategory A (ex. PS3)
– Subcategory B (ex. PS2)
– Much more Category but structure is the same (category> same subcategory)

the permalink of article is: http://www.site.com/category/subcategory/nameofthearticle.html

the permalink of archive is: http://www.site.it/category/subcategory/index.php

with che configuration standard of WordPress it’s impossible i understand because not present parameter to set subcategory in permalink

It’s possible set this configuration in WordPress anyway?

I install WP No Category Plugin to remove category base in the url.

Now the url is: http://www.site.com/category/nameofthearticle.html

For arrive a http://www.site.com/category/subcategory/nameofthearticle.html i try a solution with use tag instead a subcategory but if i set permalinks /%category%/%tag%/%post-name% not work

help me please, lost the current url & link from other site is a very problem. Thanks of all
