Allocating customers to a team and showing it in a field

[PhilSpo]

Hello,

So i have created4 different customers in Insight.

I have then created four teams and allocated each customer to a team:

How would I be able to set up two custom fields in service desk that allowed to show the customer and the team the customer belonged to in both the queue and the ticket information?

I have worked out how to create the field and what type it needs to be:

 But I am unsure how to configure it to display the objects. Can anyone offer me any further advice on this?

Many Thanks
