Add possibility to specify formulas in UltraSpreadseet the same way as it is done in MS Excel, when you can select regions, which contribute to the formula.

The same request for the WPF:

Formulas are wide used feature of Excel, it would be really great if UltraSpreadsheet can support the most convenient way of defining them.
