Once a customer creates a campaign and enrolls contacts, the campaign goes live. You can add more messages, but the enrolled contacts will not receive the new ones. Can we warn customers that when they add new messages to a live campaign, the current contacts will not get the new messages?

After a customer enrolls their contacts in a campaign and wants to edit it by adding more messages, this warning should appear.

If you add more messages to this campaign, be aware that the contacts who are already enrolled will not receive these new messages.
