A possibility would be to create a short score with all “notes” you use for instruments on your 5 bar percussion staff and then with right click and chosing percussion from the dropdown add a legend to each of them.
Assuming you have some sort of instrumentation page, eventually combined with axtitle page or composers comments before your actual piece, I suggested to put a short percussion staff with one note for each instrument in your percussion kit with the legend.
There are of course things that can’t be changed independently (like the notes and the rhythm, for example!). But part handling is very flexible, especially for anything related to layout, where the parts are completely independent from the score.
In my example above, the “Instruments” flow is shown in the part and not in the score.
I got this far, but I can’t get rid of the final bar
I went to notation options and selected barlines I selecetd the no barline in the end choices, but it does not eliminate the barline end as you can see.
I would recommend not posting personal info here, where it can be harvested by web-crawlers. If you need a response from a specific individual, better to put that info into a private message by clicking on the persona’s avatar.
