Hello,
Using templates can make work faster and easier, which is why Google is introducing custom templates in G Suite for Docs, Sheets, Slides, and Forms. Submit files to shared template galleries in the Docs, Sheets, Slides, and Forms home screens for co-workers to adapt and use as needed. These templates will help your team focus less on formatting and more on getting the work done quickly and efficiently. To use a template, go to the Docs, Sheets, Slides, and Forms homepage. There will be a selection of templates available at the top of the screen. Click on the template you want to use. The template will open in a new tab and you can get to work!
To save a file as a template you simply submit files to shared template galleries in the Docs, Sheets, Slides, and Forms home screens. This will allow your co-workers to adapt and use them as needed.
Note: The old templates gallery will be turned off early 2017. This will give you time to transition to the new galleries. A message will be shared in the old gallery letting you know the exact date. It will not take place before February 1, 2017. The Collaboration Services Team
