Support for a Foreign Key referencing a Composite Primary Key

[frobones]

Is it possible for a Foreign Key to reference a composite key?

I try something like this:

message Foo {
    option (gorm.opts).ormable = true;
    string id = 1;
    int64 version = 2;

    repeated Bar bars = 3 [(gorm.field).has_many = {foreignkey: "FooId,FooVersion"}];
}

message Bar {
    option (gorm.opts).ormable = true;
    string id = 1;
    int64 version = 2;
}

and the generated code produces this:

type FooORM struct {
	Bars    []*BarORM `gorm:"foreignkey:FooId,FooVersion;association_foreignkey:Id"`
	Id      string
	Version int64
}

type BarORM struct {
	FooId, FooVersion *string
	Id                string
	Version           int64
}

Is it possible to specify what the foreign keys reference, via https://gorm.io/docs/has_many.html#Override-References

Essentially, I want to generate code that looks like this:

type FooORM struct {
	Bars    []*BarORM `gorm:"foreignkey:FooId,FooVersion;References:Id,Version"`
	Id      string
	Version int64
}

type BarORM struct {
	FooId      *string
        FooVersion *int64
	Id         string
	Version    int64
}
