Feature: able to set an ID in limit_order_create operation

I am trying to traverse historical bitshares data and am having problems with associating fill_order and limit_order_cancel operations to their limit_order_create operations.

Both of limit_order_cancel and fill_order operations contain an order_id field in the json. But historical limit_order_create operations do not. It seems this order_id is only available and returned when the original order is created.

As a workaround I was hoping to use the order_id field in limit_order_cancel and fill_order and get_object() to get the original order. However get_object() returns nothing for 1.7.x type objects (limit order objects). Unless I am missing something, I am basically unable to link these operations.
