Today there is no easy way to produce reporting on fulfilled extra work segments/activities. It would be extremely valuable to offer that flag within the API so that I could call the activities endpoint and return activities that are flagged as extra work. In conjunction, an added "voluntary time" endpoint would be useful to in pulling and reporting on data surrounding the offered voluntary activities. The combination of the two would allow users to (via the API and/or product itself) report on dates and times that voluntary time was on offer, what type of voluntary time it was (extra or time off), what offers were accepted, and by which agents were they accepted.
