Issue: I'd like to embed an Excel spreadsheet within a PowerPoint
presentation, and show different areas of the spreadsheet in different
slides, without the whole spreadsheet being replicated for each view. I
cannot use object linking, only object embedding. Right now, PowerPoint will
embed the same file for each view, which is creating exponential file sizes.

Rationale: We often need to show multiple views of data sets that are
contained in the same Excel spreadsheet, either in different cell ranges or
in different worksheets. For instance, I might have a spreadsheet that
contains a tab (worksheet) for revenue, one for sales (and associated sales
people/revenue ratios) and one for manufacturing (and associated mfg/revenue
ratios).

If the spreadsheet is big, we'd like PowerPoint to include it only once as
an embedded object, but still allow multiple views into the embedded
spreadsheet. In the example above, I'd like to show the 3 worksheets in 3
different places of my PowerPoint document.

Linking to a spreadsheet based on a server is not practical for email based
exchange: often the server data is firewalled, or the person receiving the
presentation is offline when opening it, or...
