Send instance failure alerts to Nintex group

Currently the options for sending instance alerts are to the last person who edited the document and the workflow owners, but only if the workflow owners are added as individual users. It doesn't send instance alerts to the owners if we create a group for our team and add that instead of individuals . It would be much easier for us to manage our workflow owners when people join or leave the team if we could use the group instead. We have hundreds of workflows so updating them with individuals is painful.
