How to manage "rolling" admission groups?

I am running into a similar problem/thought for Centering Counts - 

I have heard this idea of rolling admission groups for low census clinics. We aren't a low census clinic, but we are having a hard time enrolling english speakers into our groups. We have had to cancel several English groups. The majority of our clinic (80%) is spanish speaking. We have great Spanish groups, average 10-13 in a group. But our English groups have been 3-4. This isn't an efficient use of our provider's time... I think we have low census because of 1) our population - we just have more Spanish speakers in general and 2) work schedules for English speakers. Our idea for this is offering a rolling admission English Speaking group during our late hours (we only offer 1 evening of late hours). This will be a better use of our provider's time in the morning. We will schedule centering groups once a month and fill in the 2 week visits with individual visits between centering groups. We will set 8 sessions that we will continually offer on a rolling basis. This will give all of our patients time to cover all of the sessions and still maintain a sense of continuity with patients, even though some may only overlap for a few months. (We will keep our Spanish groups the same - grouping them by GA)

I understand that Centering Counts was built for the traditional model, but if rolling admission makes group care accessible to my English cohort, could there be an option where instead the attendance being recorded by date, they are recorded by session number? And we can check off when that patient attends that *session* We can continue to add patients to that group, track their attendance to the 8-9 set sessions? So instead of dates along the top of the sessions, it's just session 1-10, and no dates are associated with them, all fields automatically are open to track attendance. Thoughts? Possibilities? 

This thread also has some helpful documents from a 2018 Circle Up Webinar on the topic:  centeringconnects.org/thread/1634/small-volume-groups-options

Because it is important to discuss age-specific growth and development and safety issues in group, I don't see how a continuous enrollment group could work for CenteringParenting.

I'm wondering if setting up a specific way of entering data for continuous enrollment groups could be an enhancement for the next version of CenteringCounts?
