Unfortunately no, but a relatively quick way to add them is to go into the history list, tap on the first entry, tap on the flashcard add + button, then tap on the scroll down button at the top right corner of the screen - if you put a finger on each of those buttons and alternate between them you can probably get through the whole thing in 3 minutes or so. (kind of awkward / silly, I admit - we'll see about adding history->flashcards in a future release, though I guess it would be too late in your case)
