[Koha] Opac login information on Import Patrons

After setup and configuration of Koha, we are now in Adding of Patrons. Mainly, our patrons are the students (College and IS) which is hundreds in number. Unfortunately, these are too many records to add manually one by one. So we decided to use the module, Import Patrons. I have tried 5 records to upload using a converted csv file of the student records. Good thing, I have successfully imported 5 samples. However, even if I have successfully added these records, the Opac Login information of the students are not included in the Import. I am just wondering, is there a way for me to add the Opac Login information of the students during the Import process? Anyone's help is greatly appreciated. Thank you in advance! Have nice day.
