this is a VERY CLUNKY reply.
first of all, i have been using DOS for a number of years and i have never seen an omit sort of thing.
if what you are doing is a standard operation for you
i would (CLUNKY)
write a batch file that would call 9 other batch files
the ninth one calling another batch file calling 9 others.
something like this
copeea
copeeb
copeed
where
copeea.bat
this would say copy c:\subdir\a*.* c:\other\
it would take about ten minutes to set it all up, but it would work
