 2. 材料复制到应用自己的本地工作区，原始文件不会修改。再次导入会先确认是否替换当前工作区；取消确认保留当前材料和核对结果。
 3. 本地 OCR 提取信息，按旧项目规则自动匹配并分类。扫描显示真实处理进度。
 4. 在“人工配对”两侧多选材料，选择分类后确认；识别失败的材料仍可人工配对。
-5. “已核对”中可查看依据、改分类、撤销及导出。自动核对结果不代表已人工复核。
+5. “已核对”中可改分类、预览材料、撤销及导出。首列勾选一组或多组材料，或使用表格上方“全选当前分组”，再点击“导出所选 N 组 PPT”；切换分组保留勾选，取消当前分组全选不影响其他分组，未勾选时不能导出 PPT。“全部”页可全选所有已核对组。行程 Excel 和个人报销单仍使用全部已核对材料。自动核对结果不代表已人工复核。
 6. 工作区自动持久化到应用沙盒内的 Application Support/ReceiptDesk；清空只删除工作区副本，不删除原始材料。
