[GORM][GO] Has many slice of many implementations

I need to register a set of entities which implement the same interface, but they must be registered in different tables as they have different structures.
I am looking for behavior similar to that achieved with jpa: Hibernate Inheritance Mapping

The following example is simplified.

type Person struct {
    ID         uint64 `gorm:"primarykey"`
    Name       string
    Identifier []identificable
}

type identificable interface {
    GetValue() string
}

type DNI struct {
    ID       uint64 `gorm:"primarykey"`
    Value    string
    PersonID uint64
}

func (dni DNI) GetValue() string {
    return dni.Value
}

type DrivingLicense struct {
    ID       uint64 `gorm:"primarykey"`
    Value    string
    PersonID uint64
}

func (licence DrivingLicense) GetValue() string {
    return licence.Value
}

func main() {
    db := getDB()
    dni1 := DNI{}
    dni1.Value = "testdni1"
    drivingLicense1 := DrivingLicense{}
    dni1.Value = "License1"

    person := Person{}
    person.Name = "test_name"
    person.Identifier = []identificable{dni1, drivingLicense1}

    result := db.Create(&person)
    if result.Error != nil {
        fmt.Sprintf(result.Error.Error())
    }
}
