I suppose as well. You'll have to check if the data selection method is available on the crosstab now ( I think they added it in 1.6).
It will require to display the value though ... But you could hide it with CSS maybe 
Or use Advance Data table from SCN Community Package (not soooo advanced) but if it does not the trick, you could always use the library and create your own extension with it.
A customer did, and it now support lots of thing (as well as hiding/enaming columns, and of course dataselection).
