you can use the gx_layercontainer type for both of your "My Maps"
nodes, but with different filters:

{
    text: "My Maps 1",
    nodeType: "gx_layercontainer",
    loader: {
        filter: function(record)  {
            var layer = record.get("layer");
            return layer.displayInLayerSwitcher && !layer.isBaseLayer
&& your_maps_1_criteria;
        }
    }
}

Cheers,
