Matrix visual - additional custom columns

[SJAP]

We'd like to be able to use columns in the matrix visual (which are wonderful because they are dynamic and filter-out if not required), but we would also like the ability to add 'custom columns' to the end of the Matrix, which are 'standalone' and aren't repeated under each column heading. For example, if we wanted a national average column at the moment it would look like this: Year 1, National average, Year 2, National average, Year 3, National average. If my example measure 'National average' could be added as a separate/custom column and excluded from the 'columns' functionality, the same matrix would read: Year 1, Year 2, Year 3, National average This is much tidier, more user friendly and potentially quite powerful. Thank you!
