Need more fine grained mandatory PR approvals at files or directory level

Currently we have set repo level mandatory PR approvers.
We have several request/usecases from our different engineering teams for a more fine grained mandatory PR approvals at files or directory level.

we had raised a support ticket for the same and got to know this feature is still not available in bitbucket. We were suggested to file a feature request for this.

https://getsupport.atlassian.com/servicedesk/customer/portal/11/BBS-102079

we want to use this feature programatically to enable PR approvers to grant/deny file/dir level permission.
Example we are looking for an api whose payload may look like as below

repo : repo-name/repo-id/repo-slug-id
inclusions : Grant PR approval permission to these file/dir paths or matching a regex expression
exclusion : Deny PR approval permission to these file/dir paths or matching a regex expression
approvers: List of approvers who these restrcition applies to.

        ],
        "exclusions": []

            "xxxxx",

            "zzzzz",
        ]
    },
    {
        "repo": "jenkins",
        "inclusions": [
            "*",
