Apart from UIEventsSelector you can also add UIStylesCallbackCreator (located at UI Toolkit -> UI Styles Callback Creator) to your game object containing UI Document to define sets of callbacks intended to manipulate style properties of your Visual Tree Asset.

Now add a new callback, provide a name for it and select target element or build a query, just like you did with events.

You can add as many targets and methods to a single callback as you want.

In order to execute given callback add it as listener to any UnityEvent and provide callback name as a string parameter.
