Change velocity of single notes without using dynamics signs.

Is there also a way to change the velocity of a single note?
For example: I have a drum score and wish the 16th bassdrum at the last 16th of 1 count to sound a liitle bitt softer then the one aftre that, that on the beat. But I dont want to show all the dynamics. It's just for the sound.
I should be handy if, for example, I could change that in "Note properties" or in the "Inspect Objecst" menu (change and and choose "Okay"which yoy can't do now. Or am I too much willing to use the program as a sequenser with this?
