Assign a note and a symbol to a particular sample

First, it must be said that the effects created by using a musical symbol from Musecore's palettes does not often give a realistic result when listening.

For example, if I want to give a slide effect to a note using the glissando symbol (or any other symbol), I will never have the same result as if I use the sample of a real slide effect from an instrument recorded in a studio. That is the same thing for all other effects such as sustained, muted, open strings, bends, staccato, vibrato, etc.

Musecore would really innovate if it were possible to assign a note and a musical symbol to a specific sample from the soundfont.

Actually I have a fretless bass with index and middle finger samples, and both with sustained, subtle vibrato, wide vibrato, muted, slap, short staccato, long staccato, etc. and in orther to be able to produce and hear the real effet, I must use at least 4 staves for just one instrument. And often I have to put a sampled note in the wrong place because that's where the effect is.

For a piano, the middle C is only one note that could be played in different velocities. But for a bass (or similar instruments), the same note could be played in different ways. And for that, I need to use different samples to create something real. Unfortunately, I can not assign to a same note (example the middle C) a different sample...

Imagine if it were possible to assign to the same note a different effect (example : playing with index and middle finger alternately using eight notes) just by choosing wich sample I would like to use for the specific note.

Wow it would be perfect!
