Why when I export a DICOM series from 3D Slicer it loses all original DICOM tags?

When I try to export a DICOM series from 3D Slicer dataset it loses all the original DICOM tags (like Study date and Time, UID, series name, series modality, etc…), Why does it work like that?
Wouldn’t it be possibile for 3D Slicer to export a series identical in DICOM tags to that imported in the dataset. This is particularly an issue when I would like to export segmentations or DICOM RT structures linked to the original series, but I’m forced to exported these segmentation linked to new untagged studies.
Can anybody help me?
thank you very much
