Tour time options should be in free periods

For recurring tour events, we use tour activities at 15-minute intervals to adjust the calendar time. It takes a long time to write all of these one by one for each day of the week. We are waiting for a practical solution update for the adjustments and the time selection area in the theme should be in the form of a selection window instead of a radio button. Please, it is not very useful in its current state. looks very bad
