How to align nodes in a palette

I have a palette with nodes like this:

I'd like to center align the nodes, how would I go about doing this? The initial palette code is like this:

var palette =
    $(go.Palette, "palette",
        {
            nodeTemplateMap: myDiagram.nodeTemplateMap,
            autoScale: go.Diagram.Uniform
        });

palette.model.nodeDataArray = [
    { category: EquipmentNodeType.CAMERA, id: "0", nodeType: EquipmentNodeType.CAMERA, text: "Kamera" },
    { category: EquipmentNodeType.SIGN, id: "0", nodeType: EquipmentNodeType.SIGN, text: "Skilt" }
];

I've found properties for the palette such as layout: $(go.Gridlayout), but so far my attempts at trying to use it to center align these nodes have failed.

The right-side palette here: https://gojs.net/latest/intro/palette.html

Does seem to have the kind of behavior I want, but it has separate nodes for the palette. And when I tried using the locationObjectName/locationSpot properties on my nodes and the gridlayout it didn't change anything with my palette, as well as messing up my diagram.
