If you would like to repeat the use of a course you have created for the Phish Remediation Step as part of a Campaign, you will have to copy the course's Fusion template, and rename the course each time you wish to use the same Fusion layout for any future phish templates as part of the Campaign functionality.
This is due to the original phish Remediation Course Reporting reflecting only the results in the attached phish template.
Please refer to "Can I Copy A Fusion Course" for further instruction.
