Ghost notes in drum notation

Is there a way to notate ghost notes in writing for snare drum or drumset. I understand that parentheses can be placed around a note, but as far as I know, that will not have an effect on playback. For further explanation of ghost notes and an example, refer to the following link: http://en.wikipedia.org/wiki/Ghost_note

Thanks. This a great program for those of us that cannot afford $300-400 for the big boy programs just for writing for drumset.
