Action Lists As Actions (Value Presets)

Action lists can be used as actions with value presets. This means that you can compose an action list and import it as an action into another action lists. The options can be flagged as editable or not.

Original request:
Ability to save values of Actions as presets to be selected in future Actions by name and/or value.
E.g. a set of preset values of color adjustments for a certain type of film or digital sensor, a variety of watermarks, different frames, blurring presets, often used colors, etc
