LabelPerFeature

One label per feature, but not supported yet in this API. The intended use is to place one label to represent each feature, even if the feature is made up of multiple parts. For example, a single label is placed at the center of a group of point parts, not necessarily at the position of any individual part.

This value can be set when labeling is authored in ArcGIS Pro, but is not supported yet in this API. If used, the placement will be as for LabelMultipartStrategy.LabelPerPart.
