Author selects the rectangle of cells that should have similar readout, activates auto-propagate of pattern. Author checks lower-right cell in block. One of the inter-cell links is getting propagated wrong, so that this reference is wrong. Author edits link from balloon text to source cell as before. Tool detects correct propagate pattern, adjusts all cells except first and last in block.
Author checks lower left cell in block, and upper right cell in block.
These now generate readouts per author desires.
