I wholeheartedly agree with this request. I do a lot of writing, and have my writing note with multiple assignments, etc. As there is a checkbox that lets you tick something off when you finish it, and because you can have multiple checkboxes within a single note, it stands to reason that you should be able to have multiple reminders per note. And yes, you can break your note into multiple notes, each with their own reminder. But for certain things, you can lose continuity and miss things/opportunities.
