It comes as two presets. Make an empty shape layer to hold the settings, give it a name, and apply Cluster Folk Settings to it. Make a second empty shape layer, name it Box 1, apply Cluster Folk Box and point it at the settings layer in its Effect Controls. Duplicate the box layer as many times as you need, then set the rows, columns, margins and animation on the settings layer; a custom order can be set on each box.
Install both under User Presets, then Shapes, and refresh the Effects and Presets panel.
