This question already has an answer here:
TL;DR: Is there a way for Siri to create an item in a specific list, and add a timed reminder to it?
iOS 9 Siri is able to add an item to a specific Reminders list in this fashion:
Hey Siri; Add bread to my shopping list
However, I am struggling to find a 'syntax' that will add an item to a list, and set a timed reminder. Here is one example of my attempts:
Hey Siri; Add book laundry time to my todo list and remind me in one hour
Siri doesn't seem to understand the "latter part" about the timed reminder. It also happens that that Siri will not place it in the correct list, but instead interpret the whole sentence as the string content of a reminder placed in the Inbox.
