get https://api.seismic.com/reporting/v2/contentPropertyAssignments
Provides a list of properties and their values for each Library content. There will be one row in this table for each property value on a piece of content. A Library content tagged with 2 single value properties and 1 multi-value property with 3 values would produce 2 + 3 = 5 rows in this table. A Library content with no property values assigned will not be present in this table. Each row represents a single value of a single property on a Library content.
