I would like to append a custom 'WAF Rule Group' to the existing 'aws_wafv2_web_acl' created by Terraform which has 1 managed group rule. I can't use the existing 'Wafv2' module, so I am planning to fetch 'aws_wafv2_web_acl' using 'data source' and attach the already built rule group(Outside Terraform) to the existing 'aws_wafv2_web_acl'. But I don't see any option to do this. I don't see a resource something like 'aws_wafv2_web_acl_rulegroup_association' to add a new rule group to existing rule groups of 'aws_wafv2_web_acl'. Is it possible to add an additional existing 'Custom Rule Group'(Created Outside Terraform) to the existing 'aws_wafv2_web_acl'(created by terrform), so that the end 'aws_wafv2_web_acl' should have 1 'customer rule group' and 1 'managed rule group'?
Thanks in advance.
