How do I hide and change restore-unison labels after a section divisi

Hello,

I am making a choir arrangement, and a part of it includes the ladies having an obligato division. I was able to just include “obligato” as the divisi label without the 1 or 2, but when I want the division to end, I am unable to change/hide the “Unis.” Label. How do I hide it, or at least change it to “End Obligato”?

It should be possible to select and hide or change the text it displays via the Properties panel in Engrave mode.
