timeshift to frame 300 but simulate as if it was frame 1

[anicg]

My animation start frame 1 and ends frame 141.

I want to simulate with frozen geometry for 300 frames, so no animation for the first 300 frames, only on frame 301 I want the animation to start as if it was frame 1, because the animation doesn't exist after frame 141.

When I use timeshift with 300 frames, It shift but my animation ends frame 141.

Any idea?

use a retime node in a shift range mode to change the seq to start from 301 then you can create a timeshift and clamp both and just add your start and end frame.
