WP Super Cache: change wp_cache_location option dinamically (to UPLOADS) ?

Hi there … I would like to change the option wp_cache_location in this way:

NOW:
/var/www/MYSITE/wp-content/cache/

I would like to put it this way:
UPLOADS/cache/

Where UPLOADS = BLOGUPLOADDIR = wp_upload_dir()

Is there a way to do that internally to the plugin ?
Is there a way to force a plugin option in functions.php to do that dinamically ?
