I have a ShortCut that will find all notes that have the tag #todo in them.
Then it reads the text until it finds the text for an open checklist items.
This shortcut will then enter text behind the open mark as the subject of the task in Apple Reminders. Like "O Create the document for Abigail" will end up in the inbox as a task "Create the document for Abigail".
It also does some checking for the tags on the notes and certain specific (groups of) tags will be transferred to the Reminders app.
For the last part the ShortCut changes the #todo tag to a #reminder tag
There is still a bug in it that the first Unchecked list item will never get send to Reminders and I can't find it.
For me this works well enough at the moment.
