Flexible selector implementation
Is your feature request related to a problem? Please describe. Forte provides the selector interface that can take data packs from multi packs. However, there can be many other use cases not covered by this simple approach, such as selecting a subset of data packs (as multi packs) from the multi-packs. Supporting such selection can simplify the processor implementation and allow one to change the target of operation at any time.
