BuiltinActions :: SetCascadingSelection - Expand current selection

With this action the current filter can be expanded by an additional condition. The currently active filter and the new condition are combined by AND. The action is not part of the default context menu, but can be provided as command or tool bar action.

The action pops up with a dialog in order to specify the filter expansion. Filter conditions are defined as OSI expressions and must be defined as valid operand.
