Via the Snapshot API, create a filter variable that can filter out successfully passed proposals. It is hard to use the 'choices' variable (together with the 'scores' variable) for this because 'choices' can contain different words and the words can be varied.

I have checked with Snapshot's dev and this feature currently doesn't exists.

This feature would be important because it will allow developers to separate out successful vs. failed proposals and do important analysis of what contributes to proposals being successfully passed as compared to those that had failed.
