Item stacker

Hey All,
I have been messing around with Arcanum and have gotten very proficient at stealing form vendors. So needless to say i have tons of items and alot of them are the same. Is there a mod out there that allows you to stack like items? i have looked and looked for a search button on the site but to no avail. (thought that doesn't mean its not right in front of me) Any help would be much appreciated!
