Feature request to make editing report columns and labels less error prone

I'd like to request that report.x.columns and report.x.labels be united so that they can be edited as one.

Example:

report.x.list=column1,label1,column2,label2,column3,label3, ...

The way TW works now, it is (too) easy to leave an error in .taskrc that causes all information to be lost.
