Partial Staff

Is the following possible and how could I do it:

I want to create a partial staff, ie. a staff that does not go to the end of the sheet. For example, in the first score on the page, I want 4 staffs (SATB). In the 2 and 3 scores, I only want 1 staff because only soprano is singing there. I want to save space by not showing the other staffs.

Thanks
