Currently total_reach is on a daily granularity, but since you cannot aggregate reach, it would be nice to see how a specific campaign/ad performed overall in terms of reach.
“How many unique people did the campaign reach?” is often more preferable to report and understand rather than how many unique people the campaign reached per day.
I request this either as a new field or replacing the current active field

This is available. The Snapchat connector exposes Total Reach (id: total_reach), the number of unique Snapchatters who saw the ads. Reach is not summable across days, so to get the deduplicated total for a whole campaign flight, query total_reach grouped by Campaign but leave the Date field out of your selection: the connector then requests period-total (not daily) granularity and returns one deduplicated reach figure per campaign for the selected date range.
