Specify a port for specific users after load balancing

Below I set the loadBalancer under sm.cfg

Sm -loadBalancer  -httpPort:13080 -restaccessviabrowser:1
Sm -loadBalancer  -httpPort 13080 -restaccessviabrowser:1
Sm -loadBalancer  -httpPort 13080 -restaccessviabrowser:1

According to the principle, after all end users log in from port 13080, 13080 is the main port of loadBalancer, so the system
Will lead the user to 13081, 13082, 13083

This loadBalancer setting, is there a way to exclude a certain port?
For example, after the end user logs in from port 13080, 13080 is the main port of loadBalancer, which will direct the user to 13081, 13083, and exclude port 13082.
