Expected Result

From the Data Export Page, when the user clicks the Store text box or the Search icon and the Store modal is invoked - when a list of stores are copied from a column in excel and pasted into the store text box, the stores should be pasted exactly like they were copied from the excel column. Example

These stores can be pasted from Excel as excepted

Actual Result

Instead only the first store is pasted from excel 03707. Please fix to allow the stores to be pasted from excel.  

Note : this works when the list is separated by a comma from a notepad.
