I am NOT a tits on the bull admin for Crescendo. I am just a JoeSchmoe user. Crescendo (let's just call is Cre from now on) puts the accent on all the notes. I tried mightily to get it on one note. No luck.... but I might be able to use separate voices. How often do you want to use that workaround? It would be ugly.
Also to note, Cre floats the accent below your lower note. Do a top of staff F and see were the accent falls. Turn that F into a chord using lower notes and the accent falls down with the chord/
