First time in the forum and a new OTRS user.

1) There is a way to associate a ticket with a company instead of or in addition to associate with a customer?
2) How to associate users customers with a company? I read some info in the web that suggested me to do this by using the CustomerId field? This means that I will create a company TheABCompany and use its identification in the CustomerId field in the customer form. Is that right?!
3) This question is related to question 1. If I can associate a ticket with a company, it is possible to add a column to the ticket lists in the dashboard showing the company name? I ask this because this would speed up the work of my agents, who would know right away from which company a ticket was created.
Well, that's it. Hope you understand what I ask.

Thanks in advance,
Bests,
