Hi Khoa,
At the moment moving or copying scans between collections option is not available via SCiOlab.
This could be done by us, as long as both data collections have identical attributes list.
The feature will be available in the future in SCiOlab as well.
As for modifying attributes, you can manually modify them in the merged collection.
Please send us the specific data collections you would like to merge and verify that the attributes list is identical.
Regards,
Ayelet
