I want to switch quickly between languages for spelling corrector as I use documents in multiple languages. When I already have a such document, with different paragraphs already set for a specific language, all the languages involved appear in the list of options for selecting the corrector language. But if this setting is not yet done for the different paragraphs, the list usually contains only the default language.
Sometimes the program is trying to guess the language but fails (shows Portuguese instead of French for example).
I know how to select a certain language if it is not listed in the menu or the taskbar list by selecting 'More' and going to a window titled 'Character' where languages can be also set:

but I find that very complicated for every selection.
Is it possible to always have three or four selected languages in the menu list that opens when clicking the language taskbar (or when right-clicking an underlined word) - first image above?
