Add multiple "tasks" at once

My shopping lists, I just have a task with the shop name and use a markdown list for the items.

Obviously you cant check those off though. I wonder if it’s possible to have ‘checkable’ list within the text areas?

Like this
EDIT: Oooh that already works! There is just no button in the edit toolbar for it…and the ‘checked’ status doesn’t save if you just click (as opposed to edit).

Markdown syntax example:

- [ ] item 1
- [ ] item 2
- [x] item 3

UI wise this feels right to me? Not sure it helps with the past to nice checklist conversion though.
