Timelines! Want to zoom out further to see years


I’m trying to start using timelines, and one thing I’m trying to figure out is how to zoom out beyond 25%. I have timeline needs for a large project where I need to see the world from 1 year to 2 years out. But, the timeline zoom control only goes to 25%

Is there any further zoom out scale control that we have or is this an additional feature that we can ask for?
