Question for any of you that have been through the E3 visa on-boarding process.

I have two TSA training ID’s. One for CTP ATP course and one for the PSA school. Must I book and pay for fingerprints to be collected twice, ie, one for each training ID number? Or can I have my fingerprints collected once by the collector and use those fingerprints for both TSA training ID numbers? To do it twice is really a lot of $$$ gone when once ought to be enough.
Thanks
