Notion: Add option to setup checkboxes as custom import filters

Hi guys, I'd love if you could add checkbox fields as one of the custom import filters field options. In my workflow, I organize tasks in Notion and then check them as "Today." I'd only want them to show up in the Akiflow inbox if Today is checked. My current workaround was to convert the fields to Select (Yes/No), but this makes it harder to organize the tasks in Notion.
