Use of parts made up of several instruments.

In a recent Tip of the week, Marc Sabatella wrote: "Another method that is useful in large ensemble scores is to create a part for each section of the ensemble. For example, one for woodwind, another for brass, another for percussion, and another for strings. Then you can easily hear any section on its own just by clicking the tab for that part. To create a part for a section, go to File / Parts, click the Single Part button, then add the instruments you want."

Indeed this way of proceeding is interesting to study large scores. But the part with several instruments so defined is static. It would be comfortable to be able to add or remove instruments, without having to delete the part and recreate another one.

Will it be difficult to implement in a future version (4 or more)?
