Dynamic Subject and Attached Filename

[Ryan Woodson]

I am trying to run a burst report the keys off a check # that has multiple payments included as an invoice. 
This report is then distributed to a single individual.
The recipient wants each invoice on a separate email but at this time the subject and the file names are static.
I want to change it so that the attached PDF files and email subject should be dynamic to the last 4 digits of the check number.
Some other constraints are that I cannot save to a network drive and then utilize a script.
I do not have access to Event Studio at this time.
