Triggering parts of a lottie

Hey Community,

I would like to make a landing page where a lottie is animated while scrolling. But the scroll progress should not be equal to the progress of the animation. Instead I would like to trigger one secund of the lottie with every scroll. So basically I would like to trigger the playback of a part of a lottie with every scroll.
The reason why the normal animate while scrolling does not work for me is because the lottie would stop while some text or objects are moving in or out of the screen.
Has anyone any ideas how to do that?
I hope it makes sense and thank you all very much for your help.
