I'd like to store a value with an exported data worksheet, but I don't want
to put the value in a cell. I just want the number to ride along with the
data worksheet, because I'm going to use the number later when I reimport the
data worksheet back into the program. The number is a value that comes from
a named range in the program that will export the data worksheet. Once I
export the data worksheet, the value that goes with it will not change.

How should I do this?
