Silly me... I didn't read the documentation well enough.

The "templateref" Element

The "templateref" element identifies a template used within the layout and assigns it a logical name for use within the Position script. The complete list of attributes for this element is below.

template Id – Unique id of the template to be utilized within the layout.
reference (Optional) Id – Specifies the alternate unique id to be used when referencing this template within the Position script. This makes it possible to re-use the same template more than once within the same layout, giving each instance a different logical id. If empty, the reference id is simply the template id. Default: Empty.
thing (Optional) Id – Specifies the unique id of the thing or pick that is associated with this template. The given object is used with the template when determining the contents of fields and such. If empty, no thing/pick is associated with the template, which means that the template cannot contain any portals that utilize a field reference. Default: Empty.
dynamic (Optional) Boolean – Instead of specifying a thing, you can flag a template as "dynamic". This means that instead of using a specific pick, the template uses the "dynamic pick" to as its context, for determining field contents and so on. The dynamic pick is only set if the layout is used on a form that's summoned via a pick (usually by clicking a button on a template for that pick); it is set to the pick from which the form was summoned. Default: "no".
ispick (Optional) Boolean – Indicates whether the template is associated with a pick or a thing. If a pick, the first pick within the container that based on the specified thing is used. Default: "yes".
taborder (Optional) Integer – Specifies the relative tab order position of the template and its contents within the overall layout. As long as the tab orders are different for all portals and templates within the layout, HL can properly sequence the flow of control. Default: "0".
