Pasting EVERYTHING attached to a staff

When I mark some bars and want to copy and paste them, I really want to paste everything, not only the notes and rests. Ornaments seem to paste, but dynamics don't.

This special case requires that everything be pasted. I have writen a condensed score, 3 or 4 corno parts writen on one staff in one voice (block chords). The score includes lots of dynamics. Then I want to explode it into 4 parts, using the plugin. The plugin requires that I do a bit of the work by hand. I create three empty staves below the 4 part staff, then I copy my 4 part staff and paste it into the three empty staves. Then I run the plugin, which nicely picks away three notes from each staff, leaving the right part on each staff. But there seems to be no way to paste the dynamics.
