Variant Group

Nohe Ka

How do I query the groups that have received variant emails from the same email blast or campaign? Ideally I would like to create a new group for both and resend an email that was sent out. I would think it would be a queriable field, but just haven't been able to find the solution. I found a thread that suggests going through the Deliveries tab, I don't have access to this tab so am wondering if that's my problem.
