Fix Magento Order CVS Export Error and Create New Columns -- 2

Ok, so we have about 4 problems that need to be fixed on our site. 1. We decided that it would be a good idea to create multiple store's all with different names so that we could separate which orders come from which marketplaces. Currently we use M2E Pro to sell on Ebay and Amazon. We created 3 stores under the same website called {our store name}, {ebay} and {amazon}. The problem is that previous orders are not updated with the current store ID. We need all the old orders to be updated with the current store ID's for the correct marketplaces that the product was purchased on. (Watch the Video. it will make more since) 2. Inside the orders section, we need to have the ability to select all the order within the filter, instead of just the orders on the first page. But we need to leave the "Select Visible" button. So it should look like this Select all | Select Visible | Unselect Visible | Unselect All 3. Every now and then we have an order Export error that comes up. It says something about FBA, but i really don't understand what the problem is. 4. The export CVS needs to look like this. The problem is that when we export the spreadsheet, it's not exporting everything in the custom tab. • Purchase Date • Status • Store ID • Item Name • SKU • Original Price • Qty • Tax Amount • Shipping Cost Paid • Total • Email The Excel export must be working before we will release the payment.
