How to go to Batch Update via Profile in one click?
Luciano,  Unfortunately this can not be added as a menu item because you are working with a search result.  

You could create a custom process that can be added to a menu.  Something like...create a custom contribution search (that filters by pending) with a hook that displays a profile that you can use to update.

If you need a consultant to do this for you, it is probably not worth it. Sorry....
