Constraining custom toolbars to one file
 

In Excel95, I have a workbook with a custom heading category (with
sub-headings and sub-sub-headings) added to the menu bar. When selected,
the sub-headings trigger the running of associated macros. If while
that workbook is open, one opens yet another (perhaps unrelated)
workbook, the custom headings also appear as options on the menu bar of
that workbook. Their presence on the menu bar above the unrelated
workbook creates confusion and the potential for inducing errors.

I note the situation is unchanged when using Excel97.

Is there a way to restrict the display of those menu bar additions to
when the applicable workbook is displayed? Might there be another way
to gain the same functionality that would eliminate the confusion?
