You already have this file and want to have the same translations for a request. With vim smart replacement :S/issue/request/ you can save some precious time.

issue:
  new: "New Issue"
  add: "Add Issue"
  issueTypes:
    functional: "Functional"
    technical: "Technical"

Copy the content of issue.yml to request.yml. Now run:

'<,'>S/issue/request/
request:
  new: "New Request"
  add: "Add Request"
  requestTypes:
    functional: "Functional"
    technical: "Technical"

That’s all what you need.
