An ACH payment on a vendor's bank statement references a name that looks like UnivofPM (or something else obscure) instead of University of Washington. How do they identify it is for UW?

They cannot have the name changed at this time but they can have the invoice number added by making a change on their Paymode account. If they have it set up as CTX or EDI 820 format, this can add information to the remittance data they see in their bank account. They should have it set up with their bank first and then request Paymode turn on the CTX on their Paymode account.
