Disable more than one word on a single prediction block

Give to the user an option to disable more than one word on a single prediction block. Ex: user types the word "big", the prediction blocks show "big whale", "big building", "big elephant". None of the predictions were memorized from previous user textings. Ideal scenario: user types "big", the prediction blocks show "whale", "building", "elephant". Reason why: sometimes the predictions will show nonsensical two or three words, like "see has been". All examples quoted here are just hypothetical. I use the portuguese language, not english. I do not care for the english predictions, that is not the problem. I only want an option to disable two or more words inside a single prediction block, so the predictions become single word by block. Because it's easier to avoid the wrong predictions than fixing the whole nonsensical two to three words by block.
