can I quickly find/replace all non existent absolute references (for
different column letters), and replace them with absolute versions of that
letter? Each different column reference, however, is matched with the same
absolute reference to row (if that helps). In other words, I don't want to
replace with the same thing, but rather I want the sheet to go through the
logic of "when I find the references of f$16 and g$16, I should replace them
with $f$16 and $g$16".

Thanks.
