Alerts feature in Redash

Hi,

We have tested the Alert feature in Redash and observed that the top row or single row is evaluated for threshhold and entire query result is sent.

Is there a way to evalaute each row value (in case of multiple row output) and when the threshhold is crossed, Alerts are sent to webhook (for example) one by one. Currently entire output is sent in a single payload.

Regards
