DS uses Comma "," as dividing digit for Webform CSV download - what about the dividing digit can be chosen?

CSV Download uses Comma as dividing digit.

When you have a webromr with a great number of of numbers, this causes every now and then confusing results when the CSV is converted to XLS. What about using another dividig digit (such as “|” as for instance SAP does) so the numbers stay complete during conversion CSV to XLS?

Or rather, that dividing digit could be chosen by user?
