Crews

i have a long text that i need to extract insights from. I target a JSON that is both imput containing thematics used for semantic reference and shall be completed/updated as output to list bellow thematics the corresponding matching insights. I split text in iterative tasks but this results in overwriting references . i wanted to have crew iteration comly updating without affecting previous round of effort . In short having more control on output .
