you could have week1, week2, week3 etc then setup schedules based on those tapes.
Or you could setup a month tape. Run a 'copy' backup manually giving the tape a name say April, then once you have done the backup add a schedule for weekday differentials using the 'April' tape.
Its still good practise to run 4 dailys, 1 weekly and 1 monthly
