Jira service desk create sub tasks automatically on parent issue

[Edvinas]

Hello,

Just started to use Jira service desk server. Is it possible to create a sub task or just automatically add some extra text to the issue description, when a customer creates it? For example: HR creates a task to prepare workplace for a new employee and then the issue is created I see subtasks or edited issue description by: "Create AD user", "Install OS".. 

Thanks.
