Response weighting for 30k respondents

Hi everybody,

we are going to start a fieldwork involving 26k respondents approx, plus 4k records to import from historical data. Those results have to be weighted on the dashboard based on each respondent's ID.
As the csv limit dimension for weighting is 260KB, we would surely go above that thresold. We tried to weight a small sample on the data&analysis, but dashboard seems not to import weights from data&analysis.
Has anyone got any idea? Many thanks in advance
