Often you will want to assign a vulnerability to be taken care of by a certain team member.
You can assign a vulnerability to one of your team members once you are on the "Findings" page.
There, you will see all the vulnerabilities that were found on the selected target.
You can select a vulnerability by checking the box on the left hand side. Once you do that, a dropdown menu will show up, where you can assign the vulnerability to one of your team mates.
You can also select multiple vulnerabilities and assign them to a team member, using the same method.
