Next update, more improved APNG, Spritesheet and GIF support will be added. This includes being able to make an animation restart/ play from frame one during blinking. This is where you could use a spritesheet to offset the blinking frames. You can technically do it in V1.3.5, but there was a small bug that may get in the way. Adding different blinking times would be messy for specific syncing, but I could try going back to the idea when I get certain things fixed/ improved!
