There is the junction table defined this way:

    @ManyToMany(() => Table2)
    @JoinTable({
        name: 'table1_link_table2',
        joinColumns: [
            {
                name: 'table1_id',
                referencedColumnName: 'id',
            },
        ],
        inverseJoinColumns: [
            {
                name: 'table2_id',
                referencedColumnName: 'id',
            },
            {
                name: 'version',
                referencedColumnName: 'version',
            },
        ],
    })
    table2instances: Table2[];

And in migration there is added one more column, let's say it's cost.

How can I change queries, that are generated to insert in table1_link_table2?

TypeORM generates queries like: INSERT INTO "test_link_question"("table1_id", "table2_id", "version") VALUES ($1, $2, $3);

But I need it to be INSERT INTO "test_link_question"("table1_id", "table2_id", "version", "cost") VALUES ($1, $2, $3, $4); and cost to be taken from Table1. Is it possible?
