Feature request: At order modification page, the user can't modify the order details

[KostyalBalint]

Problem

At the order modification page, if a user selects an orderd item for modification only the room, and the comment can be modifyed. The user can't modify the orders actuall details like size or AB/KB exra toppings.

Current workaround

Currently this only can be done if you cancel your order, and reorder the same item. This is inconvenient and can result the loss of the user's order, if someone else orders that item.

Request

Be able to change all the same details of the order, as in the order menu.
