Octave sign for high notes and second voice

Does anyone know if Musescore currently has a vertical extension of the octave line? I had to make different octave signs for the two voices. But I can't apply two lines to the same staff at the same time. Has anyone encountered a similar situation?
I also note that in addition to the notation, I also need to get the appropriate sound at the output.
If there is no solution for this problem, let me know so that I can send an appropriate request to GitHub.
