There is an additional page in the planning window where it is possible to assign an additional area or more to a course: e.g. a swimming course might require a quick warm-up before starting to swim. Therefore it is possible to add the extra area where the warm-up will take place and its duration.
In the course summary window it is also possible to add more areas to a course by clicking on details (next to the course) - other collocations. Please note that for this option the massive editing is not available, therefore it will be necessary to edit each course individually.
