I have 4 non-adjacent columns of numeric data. I would like to create a
list of each distinct entry that appears in those 4 columns. I would like to
produce something similar to that which appears in the dropdown menu after
you have applied a filter to a column [after (All) (Top 10€¦) (Custom€¦), and
before (Blanks) (NonBlanks)], but as applied to all 4 columns, and have it
appear as actual data I can enter into a separate column. How would you
suggest I proceed?
