Looking for ways to add multiple sets of numbers while keeping indices

Hello.

I am looking for ways to do addition with the multiple sets of numbers while I am keeping the indices without creating custom component. For example, as you see in the attached image, there are three sets of numbers. I want to add the numbers in indice "0", "1", and "2" in each set seperately. It would be doable to use "addition" component if the sets are a few. But if they are several, that's another story. Is there any way to add inputs to "addition" components so that I can have more than A and B? Or any other method to achieve this?

Thank you for your help in advance! and Happy new year to everyone!
