Bring field FullName of DefBillContactID->FullName to selector CustomerID

Hello experts,

I want to add field FullName of DefBillContactID to selector of CustomerID

I use the following code but it doesn’t work.

        [PXCustomizeSelectorColumns(
            typeof(PX.Objects.CR.BAccountR.acctCD),
            typeof(PX.Objects.CR.BAccountR.acctName),
            typeof(PX.Objects.CR.Address.addressLine1),
            typeof(PX.Objects.CR.Address.addressLine2),
            typeof(PX.Objects.CR.Address.postalCode),
            typeof(PX.Objects.AR.CustomerAttribute.Contact.phone1),
            typeof(PX.Objects.CR.Address.city),
            typeof(PX.Objects.CR.Address.countryID),
            typeof(PX.Objects.AR.CustomerAttribute.Location.taxRegistrationID),
            typeof(PX.Objects.AR.Customer.curyID),
            typeof(PX.Objects.AR.CustomerAttribute.Contact.attention),
            typeof(PX.Objects.AR.Customer.customerClassID),
            typeof(PX.Objects.AR.Customer.status),
            typeof(PX.Objects.AR.Customer.defBillContactID),
            typeof(PX.Objects.CR.Contact.fullName))]
        [Customer(Visibility = PXUIVisibility.SelectorVisible, Filterable = true, TabOrder = 2)]
        [PXRestrictor(typeof(Where<Customer.status, Equal<CustomerStatus.active>,
              Or<Customer.status, Equal<CustomerStatus.oneTime>,
              Or<Customer.status, Equal<CustomerStatus.hold>,
              Or<Customer.status, Equal<CustomerStatus.creditHold>>>>>), Messages.CustomerIsInStatus,
            typeof(Customer.status), typeof(InnerJoin<Contact, On<Customer.defBillContactID, Equal<Contact.contactID>>>))]
        [PXUIField(DisplayName = "Customer", TabOrder = 2)]
        [PXDefault()]

Could you please advise me?

I am wondering if it is possible to bring this field to Selector of CustomerID or not since it is in 2 level deep
