[NTG-context] \input file with parameter ?

Hi today , while writing some code I have made a mistake like this \input combine[file=depliant-block.pdf] instead of \input combine (I have combine.tex in my path of course) After a while I have thought : "Is it possibile to implement this (as a macro) in mkiv ?" I think yes, but I'm not sure (Of course, on can write things like \Input[style=combine, file=fo] and so on) -- luigi
