Currently, we can include one race at a time in the calendar, by first selecting the category (A, B or c) and then filling in the details in a window.
My suggestion is to add a new option (add multiple race days) where we have a simpler window with one line for each event, allowing us to include only the date, category (A, B, C), name of the race.
And below, a button to add more events/lines. Therefore, it would be much easier to sow race days into the calendar, especially when planning to train a larger number of athletes competing a lot of races during the season.
