How do I enter a "company" as a crew credit for specific categories?

Hey there! Hope someone can assist with the following?

How do I enter the following crew credits when I only have the company and not actual persons attached to the crew credit?

Like the following:

The Magic Light BoxDigital Film ServiceMedia Film ServiceCamera TekPhoto Hire - Cape Town

FILMING EQUIPMENT

I also have the same for Crew Agencies and Catering.

Thanks as always.
