Shorter workout plans

Is it possible to have some shorter workout plans? My wife would like to use Zwift but has more limited time than me. There are currently only a few workouts that last 30min. Is it possible to have some more shorter HIIT plans from about 20 min to 40 min in length for days when time is limited?

It would be easier for her and more motivational to come home and do a shorter workout on Zwift in her own time then to plan around a gym session.
