Empty null user to help with rotation offsets

Hello PagerDuty Community!!

I’d like to setup a repeating three week on-call schedule as follows:
Week 1: Person A
Week 2: Person B
Week 3: no oncall for this week

Is there a way to do this with the current pagerduty scheduling tool? I was thinking maybe I could create a null / empty user to create this offset but I’d rather accomplish this through a proper scheduling scheme.

Or we could have the option to add an empty user that doesn’t show up in the final schedule.

It would greatly help me out if this is possible.

Thank you in advance!
