Can NLB support mulitple target groups in one listener?

When building a network load balancer with the cloud formation, I got the following error:

• you cannot specify multiple target groups in a single action with a load balancer of type 'network' I am adding two target groups in a single default action for a network listener, the part of cloud formation is at the bottom of the page.

If I create a NLB with 2 AZs, how can I add two target groups for 2 AZs into one listener of the NLB? I thought this would make the NLB fault-tolerant, but elastic load balancing doesn't allow this.

I have to work around this by adding targets in 2 AZs into one target group associating with the listener, but this will make load balancing cross the AZs which might cause higher latency and data transfer fees for NLB.
