Is there any way to set a default on a radio button extra field? I don't see an obvious way to do it.

The problem is that it's an established site with over 1700 items that would get the extra field. I would rather not have to go in to each and every item to set the value for the new field.

test date w one xtra filed radiobutton [{"id":"5","value":"1"}]
This is going to take a sql select statement to set all the records
May be more complicated as there are probably many xtra fileds and it will have to be parsed and replaced
php foreach loop to do seperate sql stateents

Still messing with this, but there doesn't seem do be any way to do this easily. As you guessed it is going to take a script to go through the records to add it directly in to the database.
