The ability to link/match specific selected text, from around a drawing, to text in a cell of a worksheet would be a huge time saver and would eliminate manual update errors.
For example: you could select text in a text object, showing the square footage of a floor, right click to set up a link to a certain worksheet cell. Changes to the linked text, would automatically adjust the worksheet/cell text from then on.
While editing a worksheet, a cell with an established link could display with a highlighted "link graphic", that once clicked, could take you to the links layer and show the linked text, also highlighted with a "link graphic".
This would also be useful for dimensions/heights, but I can see units as an issue in this case.
