Setting EFT Layout for Expenses Pay Cycle

PeopleSoft FSCM 9.0 (Bundle 35)

We run Expense payments and Vendor payments as separate pay cycles out of accounts payable; we are using ACH processing for both.  The Expenses pay cycle is using the default Electronic Layout specified on the External Bank Account Payment Methods setup.  Is there a way to override that?

We want PPD for Expenses and CCD+ for Vendors.  To simplify changes needed if an existing voucher that is set to System Check is changed to ACH, we would like to switch our default from PPD to CCD+.  That will be great for vendors, but is messing up the Expenses payments that we still want at PPD.  But I can't find a setting, either at employee or global level, to force the pay cycle for Expenses to PPD instead of the default.
