I would love to be able to have the AI Planner plan things with the additional information of the priority level or something along those lines. This already seems to be the case with Morgen Tasks so hopefully it is not too much of a stretch.
The notion property could be a select type with the AI Planner solely looking at the ascending order so it would be up to the user to ensure 'High' is in the correct place in the list. I do not think this property needs to change any other elements besides the page where one defines the notion import configurations as well as when creating or editing a frame. Maybe for the frame, when you select the priority filter, it can briefly show you the order in which they will be prioritized. Or potentially just a checkbox someone on the frame that says prioritize based on [insert property name defined in notion import config]
