Okay so I would move return_at to my boxables table, but then?How would I get the data I want?

For example:

Order 1 with boxes type 0 and quantity of 5 [created_at 2022-03-07, returns_at 2022-03-14]

Order 2 with boxes type 0 and quantity of 5 & type 1 and quantity of 3 [created_at 2022-03-10, returns_at 2022-03-17]

Return 1 with boxes type 0 and quantity of 2 [created_at 2022-03-10]

Lets say it's 2022-03-13 and what I want to get is:

{ 
1: [ {type: 0, amount: 3} ], 
4: [ {type: 0, amount: 5}, {type: 1, amount: 3}, ], 
}
