Paper2d flipbooks rendering for animation film

Hello everyone! I’m a director who applies paper2d for animation creation, and I’m currently experiencing some problems:

When I put the animation flipbooks into sequence for rendering and then want it to be able to play from the beginning, I set the “event” node to make it “play from start”, but it doesn’t seem to work? Is there something wrong with this? Or where can I learn a tutorial on this, appreciated!

So my current process is: extract Sprites to make normal flipbooks, then place it into the Sequencer (flipbooks keeps looping), and I want to control it to start playing from the beginning at a defined frame in my Sequencer so that I can determine when the animated flipbook starts when I render it using Movie render queue .
