RTMPS pull (playback) url pays from current live while i need it to play the first ts file since stream started

RTMPS pull (playback) url pays from current live while i need it to play the first ts file since stream started.
Is there a way that i can call the rtmps url such that the playback starts from the beginning of the stream?

For example if there is an event that i have already streamed for 2 minutes and if i pull that stream into OBS studio I want OBS to play out the stream from the beginning (0 minutes) instead of playing out at 2 minutes. My OBS is automated and there is no one to fiddle with it manually and hence i need a solution that starts the stream from the beginning of the event instead of the currently playing position.
