Gant chart timeline scale

I need to create an overview gantt chart with a scope of 5 years. Thus I would like to have a timeline extending to 5 years and a quarterly sub timeline. I couldn’t find out how to do that

If the goal is to get a (printable) image which covers the whole range of 5 years, you can export your project to PNG and choose the date range on the second page of the export wizard.

Thanks for the answer. It’s a workaround but the result is not nice. I need a presentation slide which doesn’t look nice enough that way.
