Is it possible to run batch file under cd-shell boot menu?

I would like to create a few installation options of win XP and I though it would be good way to add a batch file which will execute sfx-archive from the cd, this archive will extract some file e. g. bla.txt into the hard disk and then in my RuneOnceEx I will add sections and "IF EXIST bla.txt ..." line to select what should be installed

I will have as many sfx-archives on CD as many installation options

Is it possible or maybe there is another way?

What I use is the multiple winnt.sif method described at:

This way you could run alternate version of runonce or such depending on the option you chose at the cd-shell boot menu...
