Combination problem after data upload

[Tw-ji]

To developers
When using the point cloud annotation function, I want to upload multiple groups of data as a group of continuous data and use the data, but after uploading, they are arranged as a single data. How can I upload the data to achieve this?
My current data structure is LiDAR_DATA contains Sence_01 and Sence_02, and PCD is below them。
