Is it possible to do it by session time remaining?

I was introduced to it in the F1 Gallery and am watching it with Coupang Play on, but it's neat and I like it, especially because I can even adjust the delay.

However, the session time display is counted from the start time, so it's a bit cumbersome to have to do the back calculation to synchronize. I would like to suggest that it would be easier to synchronize if I can also see it in terms of remaining time. Thank you.
