Way to quickly visualize, for all flashcards, their distribution from a document level

Suppose I clicked through to review some assorted Flashcards. Assume there are 500 outstanding cards.

Is there a quick way to view the distribution of these cards at document level only? I want to be able to quickly see the number of cards per document.

Not at the moment, unless you count going into the document’s Rem Options and starting to practice that document, then seeing the number at the top of the queue.

Is it in the roadmap?
