Yes, that's quite possible. Consider extracting all of the OPC Item Paths from the tags and using system.opc.writeValues() instead.

Do inspect the list of qualities returned to ensure everything was successfully written. The asynchronous task needs to use .invokeLater to report results back to your UI.
