Change upload location/folder

I’m trying to use this to provide my client with an option for a user to easily upload images to be used in the next-gen gallery. I’d like to be able to select the full location – ie. it’s not in the uploads folder that the images/files need to go to, but rather to wp-content/gallery/uploads. Is there an easy way to make this change? Thanks in advance.
