Like in Excel it would be nice to get an automatic summary of cells shown in the bottom right Corner (see attached file).
For example:
Value in cell A1: 20
Value in cell A2: 30
Value in cell A3: 40
When range A1:A3 is selected, the sum of those three cells should be shown in the bottom right Corner. This should be doable in reportmanager as well as in the file Manager.
