Change the format so you have 5 columns of 20 numbers. On the data page, the rows would look like:
1-20 | I | 1
1-20 | II | 2
1-20 | III | 3
1-20 | IV | 4
1-20 | V | 5
Etc with the next group being 21-40, then 41-60, 61-80 and 81-100. Then on your Style page, set Group by same hint to 5 columns. See my Binary quiz for comparison:
