It would be great if there was the ability to custom sort the order of the breakout displayed on the heatmap.  For example, we often like to use the heatmap feature to look at how the different tenure groups compare when responding to employee engagement questions.  After speaking with a Qualtrics support representative, the only option they have found is to relabel each of these groups with a letter in front of them, so they are sorted alphabetically (A - 3 to 6 months, B - 6 to 12 months, etc.).  Adding a letter in front seems like a clunky workaround and would much rather be able to customize the order instead.
