I often use Priceline in conjunction with BookWithMatrix and ITA Matrix when I need to buy specific fare classes or itineraries not available on QR website and never had a problem to upgrade my tickets (provided there’s upgrade availability).
Thank you for the clarification.
Yes I used 'F bc=n bc=q bc=s bc=k bc=l bc=m bc=v bc=h bc=y bc=b' on ITA Matrix to find the upgradable fare. O and T is upgradable with Qcredits only.
