[ic] Preventing duplicate real-time changes using PayFlo Pro

Does anyone have experience preventing duplicate real-time changes using
PayFlo Pro? Verisgn can enable duplicate charge prevention. Then you can
pass a DSGUID parameter which should be set to something unique for the
current transaction. It would seem reasonable to set DSGUIG to "<part
card number>[subtotal noformat=1]<hour of day><date>". Do I have to hack
Payment/Signio.pm to add this parameter to my PayFlo Pro query string?
