AWS Console - Network ACL - Inbound/Outbound Rules

You can from within the console use CloudShell to get a CLI for your account. From this CLI you can use the describe network ACLs to get the current, https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-network-acls.html and then use the create-network ACL with the previously exported json to create the ACL programmatically. https://docs.aws.amazon.com/cli/latest/reference/ec2/create-network-acl.html

In all reality the console should be a last resort for implementing things. Instead I would leverage the CLI or CloudFormation for repeatable infrastructure tasks.

Here's the example for ACLs in CloudFormation: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-networkacl.html
