quick update of multiple products prices

Hello

i'm trying to find a mod or extension that will allow the "price " field and the first "special price" field on all products shown on the admin>catalog>product page to be updated simultaniously.

I envisage a "new price" column and a "new special price" column beside the existing price column and an "update" button at the top of the page.

Any ideas?
