Hi all,

I need to change the field display for many2one fields. Example, 

Customer field is many2one field, related to res.partner model. By default, the system will use the display_name field to display when selected. Now, I want to change the Phone Number field to selection. 

I use the odoo.com version, and most of the configuration is set up using odoo studio.

Looking forward to your support, thank everyone.
