Moving resources to a new group

Moving resources to a new group

I am having a lot of difficulty assigning resources/accounts to a new group I created. The new group is dynamic and will collect all resources/accounts who's Customer field is "XYZ".

I am trying to edit the Customer details on respective resource group and cannot find this field anywhere.

How can I edit the Customer field on resources?
