HA Proxy Route based Config on different port

Help!
1

I have below haproxy config.

frontend main
bind :443 ssl crt /etc/haproxy/example.uat.pem ciphers DEFAULT:!LOW:!RC4-SHA:!RC4-MD5:!DES-CBC-SHA:!DES-CBC3-SHA no-sslv3 no-tlsv10 no-tlsv11
bind :80
timeout queue 10s
http-request redirect scheme https code 301 unless { ssl_fc }
acl url_bdh hdr_dom(host) -i example.uat.com
use_backend app if url_bdh
backend app
balance roundrobin
server bdh 127.0.0.1:8443 check ssl verify none

I want to create one more route as below. example.uat.com:8443/alert

It will be also on https and should use the same cert. Can someone suggest on what to add in config. The original example.uat.com should be run on 443 only.

Thanks
