Change type of existing workouts

I have created more than 100 workouts saved that I use regularly. Since I couldn't determine type when I created them, all of them are of type "Other". Now, there are suitable types for my workouts, so sat they can be divided between Strength workouts, runs and bike workouts. However, existing workouts are very limited in what can be changed. A simple type-change would solve most of my problems, so I would like to request that feature.
