Eloquent relation with two keys - laravel

Question

I am working on a team sports statistics project in Laravel.
Here is a sketch of the main models regarding this question:
class Team
// belongsToMany matches
// belongsToMany people
class Match
// belongsToMany teams
// belongsToMany people
class Person
// belongsToMany matches
// belongsToMany teams
I have also made models for the pivot tables to work directly with them. I have some stuff like goals_scored, number, position etc. stored there and it's too clumsy to use methods for updating pivot.
class MatchTeam // Participation of a team in the match
// belongsTo match
// belongsTo team
class MatchPerson // Participation of a person in the match
// belongsTo match
// belongsTo team
// belongsTo person
Is there an Eloquent way to relate MatchTeam to MatchPerson? I don't want to introduce a direct match_team_id foreign key, I want to do this using the existing match_id and team_id fields on both of the tables.
Currently I have this in my MatchTeam model:
public function matchPeople() // the roster
{
return $this->hasMany('App\Stats\MatchPerson', 'team_id', 'team_id')->where('match_id', $this->match_id);
}
It works fine. However, I am very concerned that this code is not fair to the nature of the relation - they are not related based on team_id, they are related based on both fields. I could have also written it like this:
public function matchPeople() // the roster
{
return $this->hasMany('App\Stats\MatchPerson', 'match_id', 'match_id')->where('team_id', $this->team_id);
}
Is there a fair way in which I could specify relation based on two columns in Eloquent?
Of course, this question is more out of curiosity as the actual problem of making the method is conquered.
A usage example for the curious:
$teamA->goals_for = $teamA->matchPeople->sum('goals');
