Absolutely. For that you would have to define the valuelist based on a
relationship, which would have its criteria as salaryfield =
criteriafield (for example), and you can set that it be sorted as
well. (either defining the relationship to be sorted, or by defining
the value list to be sorted -- I think either should work, but would
recomend making the value list sorted not the relationship -- that
will ensure the smaller "distinct' set is sorted, rather than the full
set including duplicates.)

Play around with defining value lists, and read up on them in the
help, to give you sense of what you can accomplish. There are quite a
few options available.
