You can certainly nlread the cif-files in a loop and save the structures as bulk configurations to an hdf5 file, so that the configurations will be accessible on the LabFloor or later for post-processing through QuantumATK scripting.
# Read a cif file as a bulk configuration
bulk_configuration=nlread("filename_configuration.cif", BulkConfiguration)[0]
# Print the bulk configuration to the log file, if needed
nlprint(bulk_configuration)
# Save the bulk configuration as an object in an hdf5-file (all the objects then appear on the LabFloor)
nlsave("filename_all_configurations.hdf5", bulk_configuration)
However, I am not aware of a straightforward Export option to create an 'filename_configuration.in' file of QE through scripting.
