Is it possible to have Roadmaps set calendar resolution in years

Is it possible to create Strategic Roadmaps in AHA that span years (2021, 2022, 2023 for example)? I’m only seeing options for 3M, 6M, 1Y. I do see under Custom I can expand the dates beyond 1 year and then by Quarters, Months, Weeks and Days. Is it possible to add Years? See attached Screenshot
