Easily Splitting Multi-Page Scans

I’m a new DTP user, and am loving what I see so far. One thing I’m looking for (and that I hope I just haven’t found yet) is an easy way to split up a multi-page scan.

For example, I’ll throw 5-6 invoices at a time in to my ScanSnap, and end up with one big PDF. Invoice #1 might be page 1, Invoice #2 might be pages 2 and 3, Invoice #3 might be page 4, and so on…

Is there an easy way to split these up into separate files inside DTP, either manually or automatically?

DEVONthink has a split document command, available from the Edit menu or from a contextual menu when a page of the PDF is selected in the PDF display sidebar. Works with RTF documents as well.
