Other marks such as ardio-buttons are supported, see /41-1-optical-marks-reader-checkboxes-radiobutton-fillable-fields-segments-etc for more details.
Checkbox grouping:
We don't support checkbox grouping at the moment. However, if the order is visually the same, then the order in the output will be the same for documents with a similar layout.
