It should be possible to add more than one day at once to the frequency "Specific Days"

Current Situation

When adding the frequency "Specific days" it is possible to add one day with one period. To add several days, each day must be selected individually.

Desired Behavior

It should be possible to add more than one day at once. To achieve this after the period is set the user can open a calendar view to select several days at once and assign them to the period.
