On TG, you can create multiple assets including Bluetooth tags by importing a CSV file - more info on Bulk Import process  can be found in this article Creating Assets in Telematics Guru

To import iBeacon tags, the CSV requires the following columns -

1) AssetName
2) TagSerial - containing the UUID, MajorID, MinorID (eg. fc4XXXXX-d6c7-464c-a56e-b0c9b051d9e0, 999, 70)
3) DeviceType

All other columns are optional.

See the CSV Template here.
