short answer: yes.
longer answer:
either generate some javascript to set the correct option or
when/if you use php to 'build' the selectboxes add the string
' selected="selected"' to the HTML of the option that should be
selected, for checkboxes you would add the string ' checked="checked"' to
the relevant radiobuttons (or checkboxes).
