CL_SALV_TABLE sort without merging

Hi all

Does anyone know how to manage a sort using the SALV factory method (cl_salv_table) - WITHOUT the sort fields merging, i.e. the same function as with field NO_MERGING in LVC_S_FCAT using old style ALV?

The sorts all work fine using the following:

DATA: lr_salv_sorts              TYPE REF TO cl_salv_sorts.

....

lr_salv_sorts->add_sort( EXPORTING columnname = 'YEAR'

                                       position   = '1'

                                       sequence   = '2'

                                       subtotal   = ' ' ).

However, the sort fields are all merged - you used to be able to switch this off using NO_MERGING in LVC_S_FCAT.....

I need to switch this merging off for ALV OM

Many thanks in advance.
