It would be an incredible extension of the possible tasks in Teach Mode if you could define certain points in Teach Mode at which r1 can ask a question. It would be like if you could initiate certain actions by voice while the task is still running, which r1 then includes in the task at this point.
I am thinking, for example, that you have a favorites list of products on a shop page and you could define the question to the user at this point. The user can then name as many products as they want from this list, which r1 then selects and puts in a shopping cart.
