Automatic A record creation on "Add Proxy Host" hook/event?

[gnud]

Are there any hooks when you create a "new proxy host"?
So that I can run some code on various events, for instance to register a new dns A record for a subdomain if it doesn't exists.

Or 3rd party libraries :) are welcomed.

One idea is in internalProxyHost.create at file backend/internal/proxy-host.js, maybe something to run shell script with another "then" Promise call.
And frontend/js/app/nginx/proxy/form.ejs in the Advanced tab a new text field "Run script after Update" :).

But that will require changing the code.
