We are also renting points and I can see the reservation on the Disney web site. I logged in to our Disney account and under the "My Disney Experience" tab on the top right of the page, I was able to link the reservation using the "My Reservations" link. You will need the 12 digit Disney confirmation number to do that. Give it a shot and good luck!
When I booked using David's, they sent me this link to check my reservation using the confirmation number: DVC My Disney Reservation
I was also able to add the reservation to My Disney Experience online. Now it shows up just like my Disney-booked POP stay and my ADRs.
