Ah, more undocumented features... :)

\definefloat  [figureitem] [figureitems] [figure]
\setupcaption [figureitem] [numberconversion=character]
\startplacefigure [title=Cows]
     \startfloatcombination[2*2]
         \startplacefigureitem [title=alpha] \externalfigure [cow] [width=1cm] \stopplacefigureitem
         \startplacefigureitem [title=beta]  \externalfigure [cow] [width=2cm] \stopplacefigureitem
         \startplacefigureitem [title=gamma] \externalfigure [cow] [width=3cm] \stopplacefigureitem
         \startplacefigureitem [title=delta] \externalfigure [cow] [width=4cm] \stopplacefigureitem
    \stopfloatcombination
\stopplacefigure

Two problems, though:
1. I tried "label=" in \setupcaption to suppress "Figure ". This does not work,
   and looking at the source I do not see how to do this...
2. Missing is some way to reset the figureitem counter automatically with each \startfloatcombination.
   It looks as if it could be a nice feature to add new keywords like "before=" and "after=".
   Maybe "beforeall=" and "afterall=", "beforefirst=" and "afterlast=", ... 

I suppose that the above brings little advantage over the \definelabel solution previously suggested.
