applying constant force only within certain part of simulation cell?

Hi all,

my system is a cubic cell filled with argon atoms. Is there a way to
apply a constant force (say, in Z direction) at each atom *only* when
they pass through an XY slab of certain thickness near the middle of
the cell?

Thanks in advance!

P.S. I searched tutorials and archives to no avail; if this was
discussed before, I'll appreciate if someone helps me pinpoint what
I'm missing!
