Change day of week

Hi. How can I change the day(s) of the week for an alarm? Thanks.

For “Quick” alarm just make a selection but pay attention to “Work days” alarms as change of days in any alarm that belongs to that group will change days for all other alarms in that group.
It was designed that way so that when you change work days in really inconsistent schedule then you don’t need to reschedule all alarms - just change days in one of them.
