Not with TIB_LookupCombo, since it is designed to automate the linking of a
value - usually a key value - to a static lookup. So, if you need to
override the stored price, then TIB_LookupCombo is not the solution on its
own.

You could add a calculated field to the dataset, e.g.
PRICE_OVERRIDE NUMERIC(18,2)

Calculated fields are, of course, not editable. Write OnCalcField code to
look for a value in an ordinary unbound edit box (labelled "Price
Override"). If a value is there, apply it to the calculated field and then
clear the edit box. At BeforePost time, check the row for the presence of
a non-null 'PRICE_OVERRIDE' and, if found, apply that value to the 'PRICE'
instead of the regular value determined by the lookupcombo.

That's only a suggestion. You might well come up with something nicer.
