@Duncan140969 Hello. I don't think there is but a less arduous a work around would be to spend a bit of time using all 3 'schedule days' (Mon-Sun Mon - Fri etc) to match your cycle and then just choose the appropriate one.
@Duncan140969 you can use @samd suggestion to make it work. It is arduous to change schedules but it would work in practice.
wk1 mon-fri use the 1 day schedule
wk2 mon-fri use the 5/2 day schedule
wk3 mon-fri use the 7 day schedule
all weekends use the 7 day schedule
A recurring alarm may help to remind when to change schedule.
