Provide a setting to control or customize the auto-generated filename for ACH/EFT (NACHA) exports.

We upload the ACH/EFT (NACHA) files directly to FedLine (the US Federal Reserve), which does not allow the parentheses and apostrophes which are in our file names. We were informed by Blackbaud support that we must manually correct our file names prior to upload, the auto-generated names cannot be changed. If we could have the ability to remove invalid characters, it would make our workflow much easier.
