Ok, and thus you augment the number of times a row repeats itself, correct?
Danger is of course that each of the text elements refer to a specific row and a column (on the 3rd tab I believe). And if you add rows in between, you have to modify the text elements that are linked to the rows that come behind/below..
So if you add a row on the 3rd position, the text elements that referred to the old row 3 (which is row 4 now) will have to be modified. And the same for all the rows after of course.
