Customer had previously used the Team field to assign a ticket to a team based on the request type that was submitted. Previously, they were able to choose to hide and preset a value against the field, but recently changes have been made and the Team field is now hidden, without the ability to predefine the field's value. 

Similar to the Assignee fields, Linked issues fields and other fields that can be found in this resource - Hidden fields and unsupported fields in request types, the customer would like the ability to set and predefine a field value for the Team field, despite it automatically being hidden.

There is currently no work around that would allow them to automate or assign an issue to a specific Team.
