Bundle-sells same quantity add to cart

I there i need a little help here, i have a variable product with options imagine a thirt with variation blue, white, black and other variation size S,M,L and i have setup three related products print on front, print on back, print on pocket and finaly an upload image to the product. I have to have separated products not options because i need that print on front, back and pocket is a product itself because i will synchronize the order with zapier to an ERP system.
So the problem is when i choose the color the size of the thirt , and if i want to have a print on pocket and in front , and add 4 thirts, on cart only transfer 4 thirts and 1 print on front product and 1 print on pocket . I would like to link the same amount of related products with the main product.
Is there any hook when i add 4 thirts the same ammont of bundle sell products transfer to cart. I already saw bundle products but that plugin creats an extra product and will mess the order with other main product.

If someone could help would be great.

Thanks
