When exporting orders: Need to be able to export - Gift wrapping, Order source, Discount used

Hi, I am having this big problem, I use this software a lot to export the orders made and process it either for sending it to my fulfillment center or my own analysis, and I have always struggled with:

1- Not having in the export fields if the customer chose if he wants it as a gift or not.
2- Beeing able to see what is this customer coming from, order source.
3- What discount the customer used in the order.

I dont think its to hard to add them to the export fields, since they are all in the data base already...
