Is there any way you can change the matrix set up so that we have an option to have the columns and rows inverted?

Like, I want to label the first column with the test names, and then be able to add columns with dates. I am attaching a rough picture of what I mean.

Also, It would be great if we could reposition the rows and columns by dragging them, instead of having to completely re-do the matrix to change the order of the columns.
