A Visio user recently asked how to add a salary amount for an Org Chart person automatically, based on their selected Level. I thought it was a bit long to answer in the forum, so I have written my answer below. It demonstrates how you can have your own custom template that works with the Organization Chart add-on in Visio.
My approach to creating a custom template that still uses the Organization Chart Add-On is to create a new drawing from the built-in template, and then to add extra properties to it.
First, select Show Document Stencil to view all of the local copies of the built-in master shapes. If they are not there, then simply drag and drop them from the built-in stencil on to the first page, and then delete the shapes on the page. This will not delete the local copies of the masters.
