Touch Lux 3 - something similar to Vocabulary Builder?

[mratyn]

I bought my Touch Lux 3 few days ago but unfortunetly i missed one thing when i was comparing it with Paperwhite 3. Does the Pocketbook Touch Lux 3 have possibility to install something that works similar to the Vocabulary Builder? If someone does not hear about it yet, Vocabulary Builder is a list of words that is generated from the words checked in the dictionary during reading.
I hope I will not have to return my Pocketbook and buy a Kindle to have this feature.

ps. sorry for my english,
this is why i need this feature
