Hi, This is just a Mod from here. All you do is upload it through your Product Manager and hey presto your done. Its active by default so theres no switching it on or anything.
I have this hack on my forums and its works well.
So all you do is go into here: AdminCP>Products & Plug-Ins>Product Manager>Add New Product>Browse then upload the XML. Thats it all done.
Heres the link:
