Study all decks at once in Anki 2.1

I’d like to study cards from all my decks at once, in random order, but retaining all study settings (new cards, reviews, lapses) from the respective decks.

What is the current recommended workflow to do this? It should ideally be “mobile friendly”, i.e. not involve add-ons.

I know Anki 2.0 had some limitations that made filtered decks unsuitable for this purpose. My collection is already updated to use the new version 2.1 scheduler.

Filtered decks in the 2.1 scheduler will show new cards in random order, but it’s only possible to set a single limit on the number of new cards and reviews - you can’t have separate limits for each deck.
