Accumulation sum in pivot table

[#1]

Hello, I have a following data

LOAD * INLINE [

Year, Country, Sales

2010, USA, 6013

2011, USA, 5295

2012, USA, 5551

2013, USA, 6932

2010, UK, 4512

2011, UK, 3976

2012, UK, 4691

2013, UK, 5276

2010, Japan, 2765

2011, Japan, 2567

2012, Japan, 3111

2013, Japan, 3234

2010, Germany, 4374

2011, Germany, 5673

2012, Germany, 4322

2013, Germany, 7654

2010, France, 4965

2011, France, 5097

2012, France, 5419

2013, France, 5732

2010, Australia, 3966

2011, Australia, 4087

2012, Australia, 2376

2013, Australia, 3784

If I create a new pivot with Year and Country dimensions

I can easily calculate:

Sales by Country  =Sum(Sales)

Total in country dimension =RangeSum(Above(Sum(Sales),0,RowNo()))

And overall Total =RangeSum(Above(TOTAL Sum(Sales), 0, RowNo(TOTAL)))

How can I calculate an overall total by countries? I want full accumulation sum only by countries through the years. This can be easily achieved by swapping dimensions, but this method does not suit me.

Thank you, it makes the expression much easier.
