Handle Custom Domain with SSL on Fabio

Problem
Currently Nomad Cluster is deployed along with fabio -> AWS Application Load Balancer. Where Load Balancer is configured with domain1.com SSL cert with ACM , where all the job deployed in nomad cluster with *.domain1.com works as expected., where route53 records are created for respective jobs.

When moving on with custom domain where as helo.domain2.com , i did map the route53 records to reroute the traffic but i am facing SSL cert issue here as load balancer is configure with different ACM.

Test Cases: Deployed NLB and mapped nomad cluster to handle the traffic , but this case how to handle multiple custom domains? Need to deploy fabio for all the custom domains which are setup ? also how to handle the traffic with SSL Certs (lets say used letsencrypt to generate CA certs )

Is there any feature or work around in fabio to handle multiple custom certs to serve traffic with SSL Certs?
