Show parent's definition in descends flashcard

Hi, my subject is I create a concept rem for example Some Theorem:: it’s definition, and descend rem with prove. I want to be able to include parent’s definition into descend flash card. I know there a lot of workarounds like use list for theorem definition and create descend (prove) for definition’s rem, use cloze flashcard etc. But all of them have side effects, changes appearance of rem references, adds indent levels and so on. There is power up tag #Extra Card Detail to show descend into parent’s flashcard just after answer was given. I think something similar (but show before answer given) for my topic will be great.
Thanks a lot! You made a great job
