How to update previous org charts created from imported info

[Dgerber]

I use the Org Chart Wizard to generate my org charts based on an Excel
spreadsheet. I spend lots of time entering the specific names and levels for
each page, where it should break, etc.

I was hoping there was a simple method to use for the next time I need to
update the org chart - without having to start all over with a new
spreadsheet.

I know in Access, you can easily generate new reports based on whatever
information is contained in the tables.

Is there a similar process for Visio. I want to keep the same structure,
page names, etc. - just have it gather its information from a NEW source
document.

Thanks.
