creating a 'patch' for excel workbooks

[Scott]

I created a workbook template that everyone in my office is
using and I need to make some corrections and add a few new
features to everyone's workbook. If I just update the
template and asked everyone to create a new workbook they
will lose a significant amount of individual data from
their files. Is there a way to create a 'patch' that
everyone can run to fix the errors and add the updates to
their existing files?

Possibly - you can write code that makes the updates.
