can I grant the role of project lead to more than one person? I would like 2 people to have project-lead type access to two different projects. How do I give them access? I see there's an administrators role. If I add these 2 users to be an administrator, they would be administrators on all of JIRA, correct? I only want them to have administrator level access to these 2 specific projects. The scheme these projects on are being used by 9 other projects so I don't want to give them access on the scheme level. I just want to give them admin access on these 2 specific projects.
