Automatically update item price on template

The desire is that if you adjust the price of an item under items in a template and you have added those items to a template, the price of the previously added/same item will not be updated with the new price. If you add the item as a new item, you will get the new price. Do not update automatically. This creates a lot of work if you have to go through all the templates to check whether all product prices have been updated.
