[scalc 4.2]- headless option for multiple sheet

Hi,

I am unable to convert xls file with multiple sheets to csv format using
the --headless option.
gnumeric utility ssconvert allows this option but I would like to be able
to do it using scalc.

Q. Is this feature going to be added in near future?
Q. Is there another way to (macros or otherwise) to do the same?

thanks
Neeraj
