How do you change which field/column in the base table is referenced by the foreign key of a sub table?

[darienmiller88]

I have two structs I'm currently trying to link via foreign key:

type Child struct{
	ID              int 		   `pg:",pk"`
	MyFK         int 
	CreatedAt time.Time 
	UpdatedAt time.Time 
	DeletedAt time.Time `pg:",soft_delete"`
 
	Base          Base	`pg:"fk:my_fk"`
}

type Base struct{
	ID 		               int `pg:",pk"`
	FieldToReference    int `pg:",unique"`
	CreatedAt               time.Time 
	UpdatedAt             time.Time 
	DeletedAt              time.Time `pg:",soft_delete"`
 }

I want the "MyFK" field of my child struct to reference the "FieldToReference" field of the base struct. How do I accomplish this? MyFK by default references the ID field instead of my target field.

Expected Behavior

The table to establish a foreign key bewteen MyFK and FieldToReference

Current Behavior

The table instead connects MyFK to ID,

Steps to Reproduce

type Child struct{
	ID              int 		   `pg:",pk"`
	MyFK         int 
	CreatedAt time.Time 
	UpdatedAt time.Time 
	DeletedAt time.Time `pg:",soft_delete"`
 
	Base          Base	`pg:"fk:my_fk"`
}

type Base struct{
	ID 		               int `pg:",pk"`
	FieldToReference    int `pg:",unique"`
	CreatedAt               time.Time 
	UpdatedAt             time.Time 
	DeletedAt              time.Time `pg:",soft_delete"`
 }

func main(){
          db.Model( &Base{}, &Child{}).CreateTable(&orm.CreateTableOptions{
		FKConstraints: true,
	})
}
