Edit the status of a Lead in a Campaign

When you use the "stop sending Mails on reply" Option, but your AI does not recognize an Auto Reply correctly, there currently seems no way of resuming the campaign for said Lead.

Am i missing it?

This should be solvable if I could edit the status if a lead in a campaign (ie remove the "Completed" tag.

There could be other reasons why this feature would be sensible.
