Hi Juraj,
Thanks for the respone as that is good information for sending emails to individuals.
I figured out what I was looking for, for anyone who may have a similar problem. Under the security tab in a standard step, there is a option for "Roles that can approve, reject, and make changes." You can select Only Listed and select your user role to that step. After adding the role this way, only the people under that role that you selected will receive a notification email.
