Options I know of:

(1) the application which originates the connection can explicitly bind
to the lo1 address (see for example telnet -s and ping -S options)

(2) the application can run in a jail(8) whose IP address is lo1, in which
case a 'bind to any' will bind to this address only

(3) use source NAT with pf etc
