aspell installs too many languages

I have installed aspell-en and aspell-de. I have expected this will give me the choice between en and de languages. However, the package has installed many versions of en and de languages and now when I want to select my spell language, I get too many to choose from. * Is it possible to configure somewhere, which languages are offered/displayed? * Can I limit the list to, lets say only en_US and de_CH ? I am sure I will never need de_LI and besides, I don't see any reason why de_LI should be a separate language anyway. I am using Debian Wheezy.
