2007 Linking Question: How do I edit links quickly and easily?

[RuthMor]

I'm formatting a bunch of charts and tables in excel for a client in Excel
2007.

I'm then pasting them into a PPT 2007 file, and then sending both to my
client.

Here's the problem: I need to link the files in such a way that the client
can seamlessly (without repasting) use both files.

And before you mention it, NO Excel cannot be embedded.

Any solutions?
