Appearance and disappearance of subtitles: Can this be defined numerically?

Hello,

I am contemplating about using the Subtitle feature asap I updatet Flame to a new version (for creating YouTube subtitles in Flame):

Can the timing for subtitles appearing and disappearing be specified numerically? For example, can the subtitles be set to appear one second after the image segment starts and disappear one second before the image segment ends?

My idea is to copy a regular segment to the same position on a track above and then change this track into a subtitle track.
(so that the subtitle segment/track has identical start and end times)
.
Is this possible, and would you recommend it?
.
Thank you!

PS
I have not updated to Flame version 2025 yet
