RelayCommand & NotifyCanExecuteChangedFor for nested Item

[michaelmairegger]

I have the following classes:

public partial class Article
{
    [ObservableProperty] // when this property changes, the test-command should be notified
    public string Property1 { get; set; }

    [ObservableProperty] // when this property changes, the test-command should be notified
    public string Property2 { get; set; }

    [ObservableProperty] // no notification
    public string Property3 { get; set; }
}

public partial class ViewModel
{
    pubilc Article Article { get; set; }

    private bool CanTest()
    {
        return //some condition on Property1 and Property2 of Article
    }

    [RelayCommand(CanExecute = nameof(CanTest))]
    private void Test()
    {
    }
}

I have a [RelayCommand] whichs NotifyCanExecuteChangedFor is not dependant on a property in the same class but on a property of a complex object. I have the following use case: The [RelayCommand] should only be notified when Property1 or Property2 has changed, not for Property3. Is it possible to notify it with this library?

This issue is similar to #755 with Prism that was easily done with:

TestCommand = new DelegateCommand(Test, CanTest)
    .ObservesProperty(() => Article.Property1 ).ObservesProperty(() => Article.Property2);
