Why not just select VS and use your brain and the DME to achieve a smooth intercept of glide slope at the same time as the localiser? Just extend the centreline from the glideslipe intercept so the go around will be available in LNAV.
Or is there a good reason to be head down messing with the FMC at 4000 ft / 15 miles from touch down that I've somehow
missed in the last thirty years?
