Directory Plugin - Wordpress user role change to "Directory Member Paid"

I can't seem to find the answer to this question. I'm using the Directory Plugin 2.0 Beta.

When a user signs up, pays at paypal and returns to my website via the paypal button, should the wordpress user role be changed automatically?

If so, I need some help because everything works fine but I still have to manually change the role which is not preferred by someone signing up (should be able to add listing right away after paying) or me, who has to keep checking frequently throughout the day...
