Yes.  If that point is a `geometrical point', you can set its
characteristic length when defining it.  That's its optional fourth
argument after the three Cartesian coordinates.  See the manual.

That's probably the easiest way, but if you need more flexibility,
there are more general ways of setting the characteristic length
field.
