Is there any way to remove category from url?

Hi, in pages url contain category and subcategory (if exist).

So, my last article is this: /homepage/computer-tecnologia/internet-telefonia-provider-adsl/come-superare-il-blocco-verso-i-siti-di-scommesse-online-r33/

i glad, if is possible, to remove category part and maintain just title eg: /homepage/internet-telefonia-provider-adsl/come-superare-il-blocco-verso-i-siti-di-scommesse-online-r33/

but i cannot found any setting for this.

url work also with: /homepage/anychars-r33/ but make redirect to full link with categories.

and no setting for Pages in "Advanced, Friendly URLs".

thanks in advace,

S.N.
