There is no mention to dynamic resources as one VMSS

### Type of issue

Missing information

### Feedback

We have dynamic elements such as one VMSS that can scale up or down, i am looking for a way to add this resource as the backend pool for one appgw, however using static ip addresses or fqdn is not working, when i scale my vmss the app gw is not capable of pointing to the new instances as the IP addresses have changed. Can you please explain how can we add one dynamic VMSS as the backend for AppGw??
