prepend default deck to all otherwise determined deck names

[jaker-dotcom]

Describe the solution you'd like

• currently you can select "logseq-deck" as default
• specifying another deck will create a deck at the sibling-level, e.g.
  • namespaces e.g. study/rockets cards will create a new sibling deck called "study"
  • or specified via page/block property
• I'd prefer having all of logseqs cards in a deck so I can study them all at once
• thus I suggest option for prepending "logseq-deck" to all otherwise determined deck names
• as a result study/rockets cards would end up in "logseq-deck::study" deck in anki

I don't think there is an alternative other than defining the deck property for each page in a namespace and typing out the default deck name for every occurrence of deck property (autosuggestion would be nice anyways).

It will help me declutter the anki home and also provide me with better learning, through interveaving / reducing context hints.

When I realised that I had too many decks, I changed all existing deck: name to be deck: top/name. It works but it is a hassle.

I will look into using tags instead, but I try to use only few general tags in logseq (idea, problem etc) so I don't think I can be happy with that option either.

See #35 who also suggests that he'd prefer interleaved learning.
