Selectively Include and exclude packages in kickstart

Hi,

The packages section of my kickstart file look something like below

%packages
libreoffice-langpack-en
-libreoffice-langpack-*

I want libreoffice-langpack-en to be included during the installation
but other language stuff need to be excluded. Unfortunately the above
packages section excludes libreoffice-langpack-en as well because of
the -libreoffice-langpack-* during pungi compose. How do i avoid this
problem?
