Using same column in rows and columns of matrix visual: Detecting row vs column context

I have different bands of customers defined based on their average monthly sales.  I'd like to display a matrix of migration between the bands i.e. how many customers have moved from band x to band y:

Customer band now                     1              2              3              4             5                6

Customer band 3 months ago

The values in the columns and rows will of course be identical.  I'm pretty sure you just can't have the same table column on the row and column of the matrix visual.  My solution is to duplicate the values in another table, providing the structure for this table. 

However, my actual question is around detecting the filter context:  I have used SELECTEVALUE, ISINSCOPE, ISFILTERED previously.  Within DAX, is there a way to detect whether these filters originate from the row context, column context or from a filter applied to the visual.  Also, is there a way to detect whether the filter is at the visual, page or report level?  I imagine you could find some use cases for that kind of information.
