Do I need to call MS to link reservations?

I was able to snag 5 more nights online for a reservation we had waitlisted. It's the same room type/view as what we already had booked for 4 nights. Do I need to call MS to link the 9 nights together or does this automatically happen?

I sent an email to MS and they were able to link them for me. I would not assume it will happen automatically.
