R42565 data selection for bursting with BIP

Hello all,

We are planning to use BIP bursting to email invoices to customers that want emails.  We do not want these invoices to appear in the pdf with the other invoices that need to be printed and mailed.  Curerntly, we have a list of customers that want email and the A/R clerk searches the invoice pdf for those customers each day and excludes the page numbers from printing.

My understanding is that we will need to create a second R42565 version to capture (and update) the email invoices so they are not included in the print run.  What data selection do you recommend to indicate an invoice should be emailed?  For example, is there a way to have a field on the F4211 populate from Customer Master during SO Entry that is available on the R42565 data selection?
