Neither of those approaches would be easy. A macro might be used to configure each Section with a 'different first page' layout, but the code for telling Word which page goes to what bin is printer specific and depends on what paper bins/feeds are attached to the printer and how those are configured at the printer. That is where the real challenge lies. Such a macro might be coded along the lines of:
Code:
Sub Demo()
Dim Sctn As Section
For Each Sctn In ActiveDocument.Sections
With Sctn.PageSetup
.DifferentFirstPageHeaderFooter = True
.FirstPageTray = wdPrinterUpperBin
.OtherPagesTray = wdPrinterDefaultBin
' Depending on the printer configuration, you
' might need to swap the above bin definitions
' around or change them to any of:
' wdPrinterPaperCassette
' wdPrinterAutomaticSheetFeed
' wdPrinterLowerBin
' wdPrinterMiddleBin
' wdPrinterLargeCapacityBin
End With
Next
End Sub
Note all the commented out alternative variables that might apply...
