+``app.project.item(index).layer(index).propertySpec.addToMotionGraphicsTemplateAs(comp,name)``
+
+.. note::
+   This functionality was added in After Effects 16.1 (CC 2019)
+
+**Description**
+
+Adds the property to the Essential Graphics panel for the specified composition, but with an additional option to give the EGP property a custom name.
+
+Returns true if the property is successfully added, false otherwise.
+
+If the property is not added, it is either because it is not one of the supported property types or the property has already been added to that
+composition. After Effects will present a warning dialog. Use the canAddToMotionGraphicsTemplate() method to test whether the property can be
+added to a Motion Graphics template.
+
+**Parameters**

+``comp``  The composition that you wish to add the property to, a CompItem.
+          Required.
+``name``  A string for the new name. Required.
