No really easy way. You can do it using pf(4) or ipf(4), with rules to
match the packets you care about and force their next hop.

See sysctl net.inet.ip.forwsrcrt, net.inet.ip.allowsrcrt. Source
routes in IPv6 are ignored (they used to be honoured unconditionally,
then for a short time they were honoured or not according to sysctl
net.inet6.ip6.rht0, but now they are ignored unconditionally).
