Is it possible to add custom entries to the language switcher pointing to the same language? I have a requirement to include Colombia, Peru and Mexico as part of the language switcher. Thing is these 3 countries all speak Spanish so is there a way to cater for this to include them in the language switcher? technically these three languages would have to point to the same spanish sub-domain

Thanks
I think you can use the hook_language_switch_links_alter() to modify the output of the language switcher. I would try to create the needed entries there to maintain the functionality to switch languages properly.
