Considering you don't want to go for controller extension..
A way is to use java script in personalization.
Simply create a RawTextBean using personalization and add the java code to change the properties.
Java script plan:
Get the handle of the items to change (like here drop down)
selectTags=document.getElementsByTagName('select') --gives list of all the select tags in the page
get ID of the select tag whose value you want to change (loop throug selectTags array).
or get it directly by getElementsByName method or getElementsByID mETHOD.
Say its handle is changeItemID.
changeItemID.selectedIndex=2
Overview of script
<SCRIPT type="text/javascript">function _checkLoad(eventXX){
--yOUR CODE FOR GETTING handle Of the select item whose value is to be changed,goes here...
changeItemID.selectedIndex=2
}</SCRIPT>
