Spelling: "Automatic by Language" won't suggest correction from multiple dictionaries

Hello.

I've configured the spelling ( System Settings | Keyboard | Input Sources | Spelling ) to "Automatic by Language" and it works like a charm. I can write in different languages (currently three British English, U.S. English and Spanish) and the language it's properly detected.

The problem appears when the spell checker detects a misspelled word. That word it's underlined in red color but when I right click it only suggestions from the dictionary on the top of the list are suggested.

Is it possible to use more than one dictionary to display the suggestions?

It's really annoying to rearrange the list when I'm switching from one language to another.

Thanks for your help.
