It is possible to add customizied ports to the default list. Just add a ACL in the "Config" > "Box" > "Virtual Servers" > "<Servername>" > "Assigned Services" > "<Servicename>" > "HTTP Proxy Settings" > "Advanced" at last line.
for HTTP ports
acl Safe_ports port <portnumber>
for HTTPS ports
acl SSL_ports port <portnumber>
In this example, the port 81 will be granted as http and https port with a comment after the hash.
acl SSL_ports port 81 # https custmized
acl Safe_ports port 81 # http customized
