Ok, I see.
Something that works mostly like what you want is the "Element boundary
mode" option in the Visibility tab. It allows to draw one glyph per
vertex (if you select "Dimension-2" in 2D for example). However, since
we still draw "element by element", if you don't define values for all
the nodes in an element, this element will be skipped (as it is not
fully defined)...
