If I understand your question well, then the answer is yes.
I have done a few such visual approaches and it worked very well.
When selecting the RWY, it will offer you to specify a distance from the runway to trace; I usually put 5 or 10nm. This puts a vector line to the RWY at the specified distance on the NAV display. It also inserts a waypoint called RX (or TX, can't remember well right now) automatically at that distance.
I then fly it in VNAV, and LNAV to that automatically inserted waypoint, setting the ALT to the RWY threshold ALT + 100, and it works very well.
Hope this helps.
