For protocols which work by initiating a request using a UDP broadcast and
expecting a reply for a specific host, is there any way to match the reply
back to the original broadcast.

An example of something that does this is smbmount, a request is broadcast to
the localnet with a port set to the netbios-ns port, and then smbmount expects
a reply from a particular host to the initiating port.
