Custom sound for grenade explosion?

[robin]

Is it possible?
"fireSound:" and "hitSound:" don't seem to do anything.

I don't want to change the sound for all the explosions.
I have a "smoke blast" sound and a "fiery blast" sound and I wanted to use them for smoke and incendiary grenades respectively (actually I'd like to use the latter for all the incendiary blasts); the high explosive would keep its standard "boom".

I attached the sounds I'm talking about, so it's completely clear what I want to do.
