Abstract: A processing device and a method dynamically aggregates desired content. A user may specify a fallback definition for a pivot point via a user interface. The fallback definition may include at least a first and a second desired value for the pivot point. Only assets, including content having metadata with values corresponding to provided desired values for one or more pivot points, may be listed in a created list of assets. The list of assets may be sorted to provide a sorted list of assets, which may be ordered such that assets having content associated with a first desired value of the fallback definition appear before assets having content associated with a second desired value of the fallback definition. Each respective asset listed in the sorted list of assets may be added to a set of aggregated content when an equivalent asset is not already included in the set.
