[tor-relays] Bridge on two port

Hello everyone, I currently run a bridge on port 8080. As I don't have a webserver running, I thought I'd also publish that bridge on port 443. For relays there is that "ORPort 443 NoListen"-Option. What is the equivalent for ServerTransportListenAddr? Is ServerTransportListenAddr obfs4 0.0.0.0:443 NoListen the right way? Is this possible at all? Does make running a bridge on two ports make sense at all?
