Referencing a Points Object in a Multilayer Object
Essentially, you only need to add in your Points object ID to the Points expression in your Multilayer object.
Below are detailed steps to accomplish this.
Find the Properties for your Points Object
Add the Points Object ID to the Multilayer Object
Open the Properties of your Multilayer Object, and paste your Points Object ID in the expression box.
When the object reloads, you'll see your points in the main map, and the points layer added to the layer control.
Note: The name of the layer in the layer control is the same as the caption of your Points object.
