xAPI event multi-choice questions - distinguish between Submit and Finish
I have a question regarding the xAPI event data we get back from the externalDispatcher call. We have an embedded multi-choice quiz on a page, and we find that (possibly after the last update to the API) each time a user clicks the Submit button to submit an answer they have selected, we get a Verb Display value of "completed" back. However, this is interferring with how we are detecting whether the user has completed the entire quiz, as we also get a Verb Display value of "complete" when the user clicks the Finish button to signify they have answered every question of the quiz.
My quesiton is, is there a standard way to distinguish between the user clicking the Submit button and the Finish button?
