Atlassian is introducing yet another early access program (EAP) for a brand new feature in Jira Service Management: Request Type Templates, which will make creating new request types a breeze. You'll have access to a library of templates, allowing you to choose the one that suits your needs. It's a faster and simpler way to create the request types your team requires (you can still customize them in project settings).
According to Atlassian, once you've signed up for the EAP, the feature will be made available to you in the upcoming weeks.
