Percussion Decorations

[Gilles]

Hi.

Is it possible to "decorate" drum notes?  Such a decoration is meant to indicate
a specific way of hitting the instrument.

For example, after a gong note (represented below with a triangle head), there 
should be a tilde-like "decoration" (to indicate that it must be scratched with
a metallic rod):
