How to show year in a timeline

Hi!

I've been commited to make possible the impossible. I've a lot of data in a Google Sheet with start and end dates from 2023 to 2028 and it is shown perfectly in a timeline. But I also have a filter and when is selected some data with similar dates (actual year) the timeline only shows months. I mean, I want to visualize year + month.

I've tried modifying the format, also using a calculated field. But it doesn't work.

I'm pretty sure this is a LS limitation but I need a way to show the year. So, any idea?
