HAProxy - Partial SSL Offloading - haproxy

Question

Currently, I'm using tcp mode to redirect SSL traffic to two backend nodes where the certs are loaded and processed. This is working as expecting, and in apache with SNI I can process the necessary domains.
For one of these domains, I have a need to move it to a different backend and server. My question - is it possible to get this setup in haproxy within the same frontend ip / port? I do not want to load ALL the certs into HAProxy - but it would be fine to load just the cert for the site that needs to point at a different backend.
Basically, can I run something like this without needed to load all ssl certs into haproxy?
acl host_mysite hdr(host) -i mysite.example.com
Update. Here are the existing config sections:
frontend http_frontend
bind :::80 v4v6
