Can you do one 4506T form when doing multiple loans to one customer

VP at a bank ($296MUSA)
If a borrower has two loans that are in process at the same time, is it customary to rely on just one signed 4506T form for both loans? It would make sense to me to have the borrower only sign one form because there is no loan number referenced on the form and you wouldn't order the transcripts twice as they are going to be the same.
