If you want, try this Action Chain while your device is connected. I use it myself.

You'll want to check the template in the single-field edit action and update the columns to your own.

program:
	input = $#kobobookmark;
	status = $#fanficstatus;
	percent = $$#percentread;

	if 
		'(In-Progress|Dormant)' in status 
		&& percent ==# 99
	then
		a = re(input, '^OEBPS/file(\d{4})(\.xhtml.*$)', '\1');
 		strcat('OEBPS/file', format_number(add(a, 1), '04d'), '.xhtml#kobo.1.1')
	else 
		input
	fi

Make sure not to open the book on device before the next update, it'll reset to the beginning.
