Once you have created a pass template, you are able to use it when applying instead of filling out the whole form from scratch.
Select the + New icon and Passes to access your pass types and templates. Select one of your templates.
Fill in the required fields and click the "Send Request" button to apply.
Handy tip; if you've requested a pass not through a template and this is a pass you regularly apply for, click the 'save as template' option once you've submitted the request so you don't have to fill the same details each time.
