[Podman] Possible to customize outgoing IP in rootless container

Hi assuming a host has 2 ips: 192.168.1.1 and 192.168.1.2 (as an ip alias). By default outgoing traffic is on 192.168.1.1 - is it possible to tell a rootless container (actually slirp4netns), that 192.168.1.2 should be used as the src ip? I would assume that this would need to be done be slirp4netns, but I wasn't able to find such an option. thanks and best mh
