Filtering Relations

My brain is locked here. I have a relation that returns multiple results lets say 20 items of an order.

I can use this relation in the order screen to show the items related to this order. I can also put it in a table and link to a custom list items screen.

However I want to filter this relation to display a subset of it. I can easily do it using filters. But how can I put it in a table? Do I have to make another relation that brings back the subset. Or is there anyway to filter a relation column and place the result into another column
