For GAGA1976:
Multiple requirements do have a place apparently, I've never tried though, If I have more than one I would usually do them one at a time while assigning an intermediate level, but it is in our manual.
If STAR = Reach FL180 by PRANG (60NM from IMPACT)
"Track direct AUGER, descend FL140, reach FL180 by 60 miles from IMPACT."
