This article apply to Urban Turtle 5.2 & later
Urban Turtle allows you to create a template of subtasks/sub-work items to rapidly populate your sprint backlog with commonly repeated activities.
This is most useful for deliverables (User Stories, Product Backlog Items, etc) that have frequently repeated task. An example of deliverable that has commonly repeated tasks would be a product release (eg tag build, update release notes, etc), change request analysis (eg review requirements, technical validation, risk assessment) or frequently adding reminders for tasks relating to your definition of done (eg have localization reviewed, deploy changes to staging, etc).
How to create a template
First, you will need to be a project administrator and go to the project administration in TFS. Click the “Urban Turtle” Tab and select “Product Backlog Templates” sub tab. From this screen, you will be able to add a new template and define the sub elements you will add when you select this template in the product backlog.
To use your template, simply go to the product backlog. When at least one template is created for your project, a new button will appear in the product backlog. Use the “Add from template” icon on the story that you want to create your multiple subtasks and there you go.
