It can be done, yes.  I am not looking for a change in semantics, just a
simple way to do it (and maybe even a fast way to do it, but that is
secondary).  If such a way already exists, please enlighten us.  If not, but
it is sufficiently simple to describe, then please describe it.  Otherwise,
I do not understand your point.

Mark.
