Is possible to save segmentation results in a single ply/pcd/obj file?

**Is your feature request related to a problem? Please describe.**
I have segmented a point cloud file into several clusters. Now, I would like to save those segments as a single file, such that when I import the file in Autodesk (or other 3D modeling softwares), these segments are recognized individually. In other words, I don't want to lose segmentation results when I save the file as ply/pcd/obj file.
