[NTG-context] vertical stretch for TABLE ?

Hi, I understood that … \bTABLE[option=stretch] … gives a horizontal stretch, so that a TABLE snaps left and right to the frame (\showframe text edges). When along table is split over several pages with \bTABLE[split=yes] it is very unlikely that the bottom-line of the bottom most row sits on the bottom-line of the text frame. Is there also a kind of \bTABLE[split=yes,option=vstretch] that gives this little stretch over the page's respective rows so that there is also a vertical snap to the text frame? Or is this a too weird request? Steffen
