Is your feature request related to a problem? Please describe.

There is a feature to avoid copying data for 2D annotation, however it's not possible to import 3D pointcloud related projects. Though the imported in archive in cvat_format doesn't create the compressed and original folders, it still requires to be copied to data cache.

Describe the solution you'd like

So I ask for a feature to use external NFS drive as a source for 3Dpointcloud and related images. Currently import of folders:

results in an error: `Could not create the task 'Dimension (2d) of the task must be the same as other tasks in project (3d)'

Describe alternatives you've considered

Enable Use cache option. Copy data is responsible for raw data, not for generated chunks. But I do not actually remember if Use Cache works for 3D

results in an error: `Could not create the task 'Dimension (2d) of the task must be the same as other tasks in project (3d)'

It looks like a bug. What CVAT version do you use?
What happens if you try to create a task without context images?

The pcd folder contains:

Task configuration:

Still fails with the same error:

Could not create the task 'Dimension (2d) of the task must be the same as other tasks in project (3d)'

I've noticed that selecting pcd files gives the same error: Sample PCD: 1713427418776507056.zip
