Just wanted to share my solution for this.
My language learning notes are classified by tags from level 1.01 to 1.20 and 2.01 to 2.20. This classification is from a university textbook, and new material which is usually following the language reference scheme A1 to C1 I am just allocating manually to those levels in bunches. It’s a one-time upfront task for new material imported which proved to be worth the little extra effort.
In order to ‘activate’ new matieral step by step climbing up the level-tags, I am using a filtered deck with the following search condition:
(is:new OR is:due) (tag:1.* OR tag:2.01 OR tag:2.02)
Once I have finished 2.02, I will just add "OR tag:2.03) and Anki will start adding level 2.03 cards.
Result: It shows all new and due cards up to the intended level (here in filtered deck “Learn by Level”). As you can see, there are thousands of cards beyond that level which are due already (e.g. 3099 in deck “5.IntgrChiVocab”). The presented approach allows me to automatically learn only up the inteded level although I have ‘learned ahead’ of that already before and thus having loads of due cards beyond that level.
