How do I adjust velocity change brought about by accents (> marks)?

This isn't an issue, exactly, or a bug, but I have a question. I've noticed that for different soundfonts, accents change velocity in different ways. It seems like accents applied to a piano using the GeneralUserGS soundfont are much louder than they sound when I change the piano in the Mixer to the default soundfont (HQ). I prefer the way the accents sound in MuseScore General HQ, but I like the overall sound of GeneralUserGS's piano over the default. Is there any way I can change how drastically an accent changes the velocity of a note?
