hello! Does anyone know if there is a way to limit matrix choices by column. For example, I have 5 choices down the left most column, and numbers 1-5 across the top. I would like users to "rate" the choices in priority order 1-5 by selecting the radio button under the other other columns labeled 1-5. The issue with the current settings, is that users could rate all the choices as a 1. Nothing forces them to pick a different number...
