The "Notify all involved" option in Recovery operation lacks the ability to specify a default Media type. This field is available in both problem Operations and Acknowledge operations but, quite suprisingly, not in Recovery operations.
This field is necessary when dealing with different media types and each media type needs a different message content (e.g. SMS and Email).
Without this field, users are forced to create multiple (duplicated) actions for dealing with different media types, which are hard to mantain.
