Ability to Control The Order in which export files are Compiled (To Enable Simple Price Changes)

To control the order in which export files are Compiled. This is to be able to make quick and easy changes to prices either globally, by category or selected products. Currently there is no way to get any consistency such that the downloaded files may be turned into an Upload "Edit" file for each product and variant because there is no control over the order of the rows when compiled. Thus the only realistic option would be to delete every product and then reload from "Add Product" files every time a change is required. This is just not acceptable and I believe that something should be done to solve this issue as a matter of very high priority. It would make a very good platform much closer to perfection!
