AWS Network Firewall can it reference an external block list

Question

Hello,

I'm trying to research if the AWS Network Firewall and the AWS WAF can reference an external block list? 
I've found articles that talked about how both applications have endpoints and APIs to reference (HTTP requests) but not one article talking about whether its possible for the AWS Network Firewall and the AWS WAF to reference a external dynamic list where it would block the IPs on that list.

Any help would be appreciated.

Yes both AWS Network Firewall and AWS WAF offer functionality to reference external block lists of IP addresses for blocking traffic. You can leverage these capabilities to enhance your security posture by blocking known malicious IP addresses and mitigating threats to your applications and network infrastructure. 
You can refer to this AWS documentation for in depth about this :-https://aws.amazon.com/waf/faqs/

Hope it clarifies and if does I would appreciate answer to be accepted so that community can benefit for clarity, thanks ;)
