[NTG-context] Spacing after combination

Hi! Is there a way to influence the spacing after a combination is placed? \useMPlibrary [dum] \starttext \startcombination [2*2] \startcontent \externalfigure \stopcontent \startcaption Foo \stopcaption \startcontent \externalfigure \stopcontent \startcaption Bar \stopcaption \startcontent \externalfigure \stopcontent \startcaption Lorem \stopcaption \startcontent \externalfigure \stopcontent \startcaption Ipsum \stopcaption \stopcombination \samplefile{knuth} \stoptext I know I could wrap it in a float and use the float to control the spacing, but it would be great if I could do without that float.
