Multiple outputContainers in UnityEditor.Experimental.GraphView.Node

Hi there,

playing with UnityEditor.Experimental.GraphView.Node. Looking for way to establish multiple outputContainers (maybe array of them :face_holding_back_tears:) instead of single one.

Can see that:

    //
    // Summary:
    //     Outputs container, used for output ports.
    public VisualElement outputContainer { get; private set; }

any tip / advice how to make it happen?
