Possible to Set repeating group with these parameters?

i was wondering if it was possible to set a repeating group on things created within a certain timeframe, like


[
[ all stuff from this week
[


[
[ all stuff from two weeks ago
[


[
[ stuff from 3 weeks ago etc
[


i essentially want to be able to organize posts on my per weekly basis, when you click on a cell it’ll dive into posts from that week…

does anyone know how to get the repeating group to be expressed in this way?
thanks ahead!
