Specifiy tracked documents for spaced repitition

[Anhsirkz]

Is there a way to achieve the following from within the plugin:

Lets say I have a directory containing 20 notes on lectures and courses. I want to have listed three current files in the Current Flashcards pane.
Now the plugin shows all repetitions of 20 notes that are due and are specified in each document, which does not scale really well if one were to have more than 50 notes. As of now topics aren't organized then and I would prefer to study flashcard sets by lecture topic rather than randomly through 'new' and 'old' sets.
Is there a way to tag a current document. Your help is much appreciated. Thanks
