Working space - possible feature

I noticed that Finale [now moribund ..] has a feature for extracting notes from chords.

This is useful for extracting lines fo play on other instruments from a piano score.

Almost the same functionality can be achieved in MuseScore by using the Explode feature.

If a chord has N notes, then use N [possibly N+1] blank staves. Copy the section to be expanded into the top stave, then use explode, and the staves below will then be populated with the notes from each chord in order.

Often these staves can then be copied - for example into a brass section, or a vocal section.

With some awareness, the explode operation can be done in place directly into the section to receive the exploded notes.

However sometimes it is better to put extra staves into the main scores in order to do these operations.

It also doesn't work quite so well if the stave with the chords contains multiple MuseScore voices.

A way to make this more palatable might be to have a subsidiary workspace tool - a set of additional staves used only for temporary work. This would avoid having to create extra work space in the main score, and possibly having to do a later tidying up operation.

Has this idea been suggested before? Indeed it might be useful to allow more than one such temporary work space - each one named - so that future changes and modifications could be easier.
