[Defender Pro] Hex values in URLs for 404 lockout

I use Gravity Forms with file upload fields and used to be able to add the temporary file URLs that plugin creates to the whitelist in 404 Detection so they don’t trigger lockouts.

But that’s not working any more as hex values I need in the URLs get stripped out since version 2.2.2 when the ability to ban by filename/extension was added.

Any way we can get that to work again, with some filter maybe in functions.php, so the hex values in URLs don’t get stripped?
