Hi - this is a great suggestion! I assume you are referring to the choice response? Do you have any specific ideas on how the feedback should be provided to the participants? Off the top of my mind, an intuitive way might just be displaying the time elapsed as participants are responding. When they lock in their choice, the timer freezes and thereby reports how fast they are.
Currently it's not possible, but we can probably schedule the feature to be included in the December grammar update.
