delete all or batch delete

We have heard at least 2 teachers reporting making mistakes of adding a school roster (1000 users) or a merged roster to the tool accidentally (300).. The first one reported to us and manually deleted 900+ users..

In this situation, if they need to save the campaign data, the only option is to manually delete those users instead of creating a new class. This feature should make their lives easier..
