Make "NPM automatically create custom DNS with pihole" an option.

[Haui1112]

I'm using nginx-proxy-manager and it is one of the greatest tools ever!

I would like to automate the creation of custom DNS Records in Pihole so users can have fully automatic domain creation in a closed off environment.

The API of pihole can do this, here's the documentation: https://github.com/pi-hole/web/blob/6c320a42574f9f0944ded71d84b7331557dbc6ea/api.php

Is your feature request related to a problem? Please describe.
When I create a new proxy host and try it, my computer doesnt route to it since I'm in a closed off home network and pihole needs to know which IP belongs to the domain.

Describe the solution you'd like
I would love to have nginx proxy manager communicate any new, changed and deleted domains directly to pihole if the option is ticked and the contact info (web adress, docker adress, whatever is possible) is ticked.

Describe alternatives you've considered
An alternative would be to have pihole wildcard any subdomains of the base domain to the server IP but this leads to the issue of having to use different domains for different machines which isnt necessary with the above solution.

Additional context
I believe this is the entry of pihole API to talk to:

elseif(isset($_GET['customdns']) && $auth)
{
	if (isset($_GET["auth"])) {
		if ($_GET["auth"] !== $pwhash) {
			die("Not authorized!");
		}
	} else {
		// Skip token validation if explicit auth string is given
		check_csrf($_GET['token']);
	}

	switch ($_GET["action"]) {
		case 'get':
			$data = echoCustomDNSEntries();
			break;

		case 'add':
			$data = addCustomDNSEntry();
			break;

		case 'delete':
			$data = deleteCustomDNSEntry();
			break;

Again the above mentioned documentation: https://github.com/pi-hole/web/blob/6c320a42574f9f0944ded71d84b7331557dbc6ea/api.php
