Sounds like a good description of "sub tasks" to me.
For Server, DC and Company-managed projects, your jira or system admins will need to add one or more sub-task types to your project (via the issue type scheme). Once that is done, you'll find anyone who can create issues in the project will have "create sub-task" in the options menu for standard level issues.
For team-managed projects the project admin can enable sub-tasks in the issue settings for it.
