Is it possible to attach more than 5 Security Groups in Application Load Balancer

Hello.

The quota associated with the security group's network interface is 5, so I think it would be possible to set it to 6 or more by increasing this.
This quota is per region, so please select the region you are using when applying.

I tried it in my environment after applying for a quota, and it was possible to set 6.
