How to use any dictionary of hunspell?

[Jose Ramom Flores das Seixas]

Hi:

I use Linux Mint.

By default, LyX only allows you to work with certain locales for 
spell-checking, synonyms, etc. For example, the Portuguese language has 
multiple variants: pt_pt, pt_br, pt_ao, pt_mz, pt_gw, as well as 
pt_pt-ao, pt_pt-preao... but LyX only lets you work with pt_br and 
pt_pt. Is there any way to choose one, or more, of the other variants?

In linux many programs—such as Thunderbird, Firefox, gedit, xed...—allow 
to use any dictionary found in the /usr/share/hunspell directory. Of 
course I can make symbolic links inside this directory, but it’s a 
workaround that sometimes causes more problems than it solves.

Regards
