If I'm understanding your question correctly, you can have multiple segments on a panel that consists of a cohort table. If you want different segments per cohort table, you can wrap each one in a panel and then add the desired segments to each panel. In the future, we are considering adding segmentation capabilities to both the inclusion and return metrics as well (in each cohort table).
Thanks for the feedback. We are working on some improvements to the Cohort table one of which is adding multiple segments to both the inclusion and return criteria.
