I have a root deck and within that deck I have multiple subdecks. Now I would like to randomly select a subdeck, then study the first card (wrt the insertion order) within that subdeck then again select a new subdeck and study the first card due from that subdeck and so on…
Root Deck
Subdeck A
Card A1
Card A2
Card A3
Subdeck B
Card B1
Card B2
Card B3
Subdeck C
Card C1
Card C2
Card C3
For example the cards should be displayed in this order :
Card B1
Card A1
Card B2
Card C1
Card A2
i.e. random subdecks are selected but within that subdeck that cards are displayed in insertion order.
None of the options will give you what you want. The best thing I can offer you is to select N cards from each deck in ascending order. And sort them randomly.
New Card Gather Order
Deck: gathers cards from each deck in order, starting from the top. Cards from each deck are gathered in ascending position. If the daily limit of the selected deck is reached, gathering may stop before all decks have been checked. This order is fastest in large collections, and allows you to prioritize subdecks that are closer to the top.
New Card Sort Order
Random: Fully shuffles the gathered cards.
In order for the upper deck to collect all the cards, you need to set the number of new ones equal to or more than the number of new ones from the lower decks.
To do this, change the number of new ones only at the top deck (total).
