Load balancer + security groups

I am trying to accomplish whats written in this blog https://www.vmguru.com/2016/11/nsx-edge-load-balancer-nodes-not-accessible/ but with vra7

I.e I deploy the load balancer and the vm's from a blueprint. the vm's belongs to a security group. But the loadbalancer can't access them because I cant add the load balancer to the SG. What I need to do is to add firewall rules with the ip of the load balancer to a security group which includes the deployed vm's. Are there any prewritten integration for this?
