Is it possible to create one-line/one-child flash cards, or flash cards with non-card children?

I take notes in the form

- front of card -- back of card
    - further info
    - further info
    - front of card with further info -- back of card
        - further info
        - further info
        - front of card -- back of card
    - further info
    - front of card -- back of card
        - further info

etc. I can’t seem to figure out if it’s possible to write like this in Logseq, where if something is the front of a card, everything descending from it is the back, or if it’d be possible to write a plugin enabling this. The default makes it very awkward to take notes about many topics for me.
