Good catch, JDH - we set things up that way so folks could do exactly what you describe. Just re-read the in-app help, and we mention both lists, but don't lay out the implications too clearly. I'll file a feature request to clarify that in the help, and file the request about mapping lists to contexts, too. Thanks!

If you want to add a timed item to a specific list, just say "Remind me to <thing to remember> in <name of list>." Siri will do that, then ask you for the time when you want to be reminded. Siri is sometimes a bit picky about what it thinks you meant, but we've gotten it to work often enough we know it's possible. :-)
