Is there a built-in event for whenever a transform in a scene has been changed?

I’m checking for whether doorways in my game are obstructed using raycasts. This isn’t done at runtime but rather while in the Editor, and I’d like to make a script to automatically do that every time a GameObject in the scene is moved or rotated, as it could potentially have changed the state of obstruction. The reason this isn’t done at runtime is because it’s related to a tool for level designers on the project to use while designing the level in the editor.

I’ve tried looking in the documentation for an event that I can subscribe to that gets called whenever a change is made in the Scene, but the closest I could find was EditorApplication.hierarchyChanged which doesn’t get called when objects are simply moved or rotated.

I use something like this together with Gizmos. How about:

private void OnDrawGizmos()
{
	if (transform.hasChanged)
	{
                // Run your code here
    }
}
