Thanks Adriano,
If I read your example correctly you are saying that I can script it and place the values in between the:
<wpcf-fields-select-option-0d1c863c4a0275b46a397ff867e70846-2>
<title>California</title>
<value>california</value>
</wpcf-fields-select-option-0d1c863c4a0275b46a397ff867e70846-2>
(For example)
But where does the UID (0d1c863c4a0275b46a397ff867e70846-2) come from?
I've added tag data using a script using this method before but I've not seen these ID's.
