Hi, yes it's possible. You need version 2024.1 and then you use ALT key + scroll backward or forward with the mouse wheel while hovering above the cell. This will change the time reference of the cell.
I added some documentation here: https://www.kinovea.org/en/forum/viewtopic.php?id=1973
It won't automatically import the key images you have previously selected. It's an independent process, you'll have to configure the kinogram for say, 5x1 cells first, and then move each cell in time to find the right spot.
