Replaces the campaign's suppression-list assignments with the supplied set (a full replace, not an incremental add). suppression_list_uuids must be present; send an empty array to clear all assignments. Only UUIDs of suppression lists owned by the account are applied -- unknown or foreign UUIDs are silently ignored. Returns HTTP 200 with an empty data. Read the current assignments and the available lists first with get_campaign_suppression_data.
