DA:O, How to change default screenshot folder

I have my game installed on a secondary hard drive, and while I'd love to be able to save all my screenshots, my main SSD where I keep my OS is not big enough to hold all that data. I'm trying to find out how I can change the default path of my screenshot folder from my C drive "my documents" folder, to the DA:O installation folder on my D: drive, which has a terabyte of space waiting to be filled.

Can anyone give me a quick tutorial on this?  I tried mucking arund in the config file, but couldn't find it anywhere, just the options to take them or not, upload them or not, etc.

Thanks.
