Hi @GLewis5,
Have you checked out the SN Docs site?

"An action can be prevented from propagating further by calling action.stopPropagation() in an effect function or by setting stopPropagation: true in the actionHandler config. This prevents any ancestor components from being able to handle the same action.
Note: If you want to stop the propagation of an action that is originally dispatched by the same component, you must use the stopPropgation: true configuration of the action handler. The dynamic action.stopPropagation() call in an effect function will not work in this case. This is because an action handler for the originating component is called after the action has finished propagating."
