Adding Third Stave mid-way through score with clef
I am trying to write something that has a third stave for the last few bars. I've done this a few times by selecting the option to hide unused staves. This option will, however, draw the whole line if there are notes on it when I only want the last few bars to be drawn. When making the empty bars on this line invisible, any clefs in those bars are also made invisible.
I have also found that the option to hide unused staves still leaves the stave drawn at the start of the piece and even when making it invisible it still takes up the space it took before making a large gap in the score.
Is there any way to achieve the effect shown below in musescore?
