How can I the suppliers product and services in bulk upload

I need to import the supplier's products and services in a bulk upload. I found the FBDI template but the supplier number is not included in the template as in the picture below:

Kindly note the preparing of uploading sheet takes a long time and the supplier name may be changed during the preparation.

Is there any other uploading sheet template to update the supplier product and services category? Or can we add a new column in the existing sheet to add the supplier number?

Thanks,

Ibrahim
