Pastes the previously copied cells to the end of the exsiting value in the currently selected cells in the Edit Pane, adding a space between the original value and the pasted value.
This includes multiple values if the copied cells have them.
If the copy area was larger than the selected paste area, then only the required number of fields are pasted.
If the copy area was smaller than the selected paste area, we reuse the copied fields in order to populate the paste area.
