Addt command format

[xxzz-tt]

Since the app is targetted at fast typists and exercise templates are also indexed, it would be better if the user can use the addt command with the index of the exercise templates as it is less prone to typos and faster to type.

Team's Response

If there are a lot of templates, it might not be very convenient to look for the index of the template.
