DEV Testing

I was just reading up about the testing feature within the NWC workflow designer. I've used this feature before and have found it helpful for some of my less complex workflows for testing simpler ideas. I've found that I do not make use of it with my production workflows however because it still sends out tasks and emails to whoever they are typically assigned to. When I do testing I can't be sending my vendors and coworkers extraneous emails. It'd be helpful to have the testing feature default all emails and tasks to my own email rather than running them per normal.
