Score effects that control articulation will generally work in Notion libs*, the program/programmers know what is in the sound lib and how to switch them. These are different and not consistent in other libs. It is therefore difficult to map and keep up with hundreds of different vendor libraries, I expect.
To get a trill for example, I sometimes look up the keyswitch in GPO sample interface and include the note, or switch to a secondary part; this gets the right sound, but is a lot of setup and is a challenge in the score. A strategy I use is more often is to switch instruments inline from the GPO legato flute to the Notion flute right before the trill, and switch back again afterward, and marking the instr 'hidden.'
*Not always though. Some marks which ought to work (on N3 instruments--or at least approximate the effect--don't. An example was something I was working on today is the case you describe, where I wanted fingered tremelo on clarinet, and it didn't create the effect, and I had to notate it. I just tried this on other parts, and found the following: triple-line trill produced single note on 4 of 5 wind instruments, but double-line trill, sounded in all 5 (more staccato-like). On oboe, where both sounded, I got faster sound on 2 than on 3. Maybe someone else might try this simple test?
