condition for combo deal

[info17]

Is it possible to make the condition for combo deal to require the same number for all items?
It seems that the condition is calculated as total number of all items, not individual item.

i.e.
But 1 Product A + 1 Product B Get 1 Product A Free

I tried to setup but 3 Product A + 1 Product B gives 2 Free Product A which should not.
It should be:
1 Product A + 1 Product B gives 1 Free Product A
2 Product A + 2 Product B gives 2 Free Product A

You can do this programatically by using this filter:

add_filter( 'wjecf_free_product_amount_for_coupon', function( $coupon_qty, $coupon ) {
 //calculate the quantity and return it...
 return $coupon_qty;
}, 10, 2 );
