Optimization of transport costs for the customer

[Michel_Philippines]

Hello,

I am looking for an addon to generate upsells based on the weight of the package and the cost of transport.

Let me explain, the majority of carriers operate by weight bracket 0.001 kg 1kg = $ n, 1.001kg 2kg = m $
I would like to be able to offer my customers an optimization of transport costs. Let's say that his purchase is 650gr, he has 350gr left to add another product without increasing transport costs.
So to be able to offer him a list of products with a maximum weight of 350gr sorted by category and by price.

Do you know an addon that does this, no matter how much I look, I can't find

Thanks in advance
