Join conditions on entity relation

Is it possible to define a custom join condition for an entity relation? Some pseudo code to illustrate the intent.

type Position = 'pg' | 'sg' | 'sf' | 'pf' | 'c';

class Player {
    id: number;
    name: string;
    position: Position;
    teamId: number
    @ManyToOne(type => Team, team => team.players)
    team: Team;
}

class Team {
    id: number;
    @OneToMany(type => Player, player => player.team)
    @JoinCondition('team.players','shootingGuards','players.teamId = team.id and players.position = "sg"')
    shootingGuards: Player[]
}

I know this is possible through the querybuilder, but looking at the docs there does not seem to be a way to define something like this on the entities itself

This is a feature I would really like to see. Any updates on if it’s planned for implementation?

+1 Leaving my use case here:

class Account {
  @PrimaryGeneratedColumn()
  id: number;

  @OneToMany(() => AccountUser, (user) => user.account)
  users: Promise<AccountUser[]>

  @OneToOne(() => AccountUser, (admin) => admin.account, {
    where: { isAdmin: true },   // --> Would be great to be able to specify such a condition somehow
  })
  admin: Promise<AccountUser>
}

class AccountUser {
  @PrimaryGeneratedColumn()
  id: number;

  @Column()
  isAdmin: boolean;

  @ManyToOne(() => Account, (account) => account.users)
  account: Promise<Account>;
}
