Automatically add new files within a folder

Hello,

I'm a new user to TortoiseSVN and I have one small issue. I'm working on a
game project, and there is one folder (an Art Assets folder) that
automatically gets any new art placed within it. My problem is that I would
like it if any file placed within this folder would automatically be added
to the repository. It's annoying to have to to add any new files while
working so I can have them safe in our repository. I know that only art
assets will be placed in this folder. A program that we don't have the
source to automatically moves them there so we can't modify the program to
automatically add the files to our repository upon adding.

Is there any solution for this? If there isn't, I would greatly appreciate
it if this could be considered to be added for future revisions of
TortoiseSVN.
