PP & Excel Data for Charts

[Dave Eade]

Hi,

I've just inherited a slide deck that has about 20 slides, each displays a
chart driven from embedded excel data.

This is no problem, except each week every slide has to be manually updated.

The data which is used comes from one excel dump out of another system.

So to my question:

Is it possible to have multiple slides linked to one excel spreadsheet -
then I only have to do the update once and it all updates automatically?

Thanks Guys & Gals

David
