As I described in [this recent post](https://discuss.elastic.co/t/bucket-selector-aggregation-script-access-doc-index-field-value/35516), you might be able to achieve this by creating a separate wedges-centric index and index your data twice. In your current index you store all the individual state changes while you in the widget-centric index store only the current state of each widget, where each change results in an update.
