Copy a cell value to other cells with drag-n-drop, similar like it's in Excel.

Is it possible to add feature of copying a value from a cell to other cells?

The feature can be implemented in similar way like it's implemented in Excel. In the bottom of right corner can be a small dot or square and when you hover over it, the cursor changes to a cross. Dragging the cross and highlighting other cells vertically or horizontally, the value will be copied to the highlighted cells after the cross is dropped.
