Did you (or has someone else?) tried to use task groups (object type TG)? If that worked, you could group your tasks into one task group, and use that group in SWNCONFIG, etc.
In general I would perhaps avoid using wildcards even if they worked (or at least be extra careful with them). Perhaps you could make it work now (=it selects only the tasks that you intended), but you will never know what happens in the future: someone (or SAP) creates new tasks, which fits into your wildcard criteria, and you users will be getting some notifications that they are not supposed to get (this is especially valid concern if you would be using the custom created tasks "TS9*" in your filter).
Kind regards,
