Way to make "Look Up" without internet on

Every time I try to look up a word using the iPhone app with Airplane mode on, my phone will only look up whatever word I highlight using an English dictionary instead of any of the Greek ones.  I tried downloading some of the Greek dictionaries/lexicons and this didn't change anything.  Is it possible to get the app to do a proper Bible Word Study look up without the internet on?  Maybe downloading certain resources, or anything?
