Remove languages in translations?

I use spell-checker for 4 languages, en, de, fr, and lb.

If I enable Spellchecking and writing aids for en, de or fr in System -> Administration -> Language Support there will be multiple versions of each language available, e.g. en , en_CA, en_GB, ...

Is there a possibility to select only one of those language versions while enabling the language, or removing the others afterwards. It would be enough to remove them from the selection menu.

I would like to use the version which is equal to the country the language originally comes from: e.g. de_DE, fr_FR, en_GB. For lb there is currently only lb_LU so there is no problem (yet).

Instead of 4 languages I currently have around 20, which is kind of annoying when switching the language ( which I do quite often).

There might be a similar problem for the menu translations, where if I understand correctly you can choose the order in which translations are applied if they exist.

Any suggestions?

What worked for me, is de-installing the aspell dictionary, because it contains all four English versions in one package, and then installing/de-installing the localized dictionary’s for hunspell. so you can choose to only install the en_EN but leave en_CA uninstalled . And because Synaptic gave me no dependency warning when de-installing aspell plus its dictionaries it should still work in all programs.

[edit] only works for english. french, and german are also all-in-one packages for myspell/hunspell

[edit2] what now really works, but may not be the best solution:

delete de dictionaries/links to dictionaries from /usr/share/myspell & /usr/share/hunspell after de-installing aspell. Only flaw may be that hunspell only has an en_US dictionary, but no british version
