How do SourceCache or SourceList operate after binding?

[NicksGhost]

Hi, I would like to know if SourceCache or SourceList can still modify/add/delete filtering or sorting functions after binding the subscription?

public class ListViewModel : ReactiveObject
{
    private readonly SourceCache<ItemViewModel, string> itemsCache = new(o => o.ItemId);
    private readonly ReadOnlyObservableCollection<ItemViewModel>? items;
    public ReadOnlyObservableCollection<ItemViewModel>? Items => items;

    [Reactive]
    public ObservableCollection<ItemViewModel>? Source { get; set; }

    public PackageInfoViewModel() 
    {
        itemsCache.Connect().Bind(out previews).Subscribe();
        this.WhenAnyValue(o => o.Source)
            .Subscribe(o =>
            {
                 // FIXME: I wish I could add a filter for itemsCache here
                 // itemsCache.Filter(o => o.Id == 1) ?
            });
    }
}

Or do I have to recreate a new SourceCache?
