Thanks for adding our suggestion.
When checking the copy billing to delivery checkbox, the shipping quote should be triggered. Also, if the copy checkbox is checked and the billing saved addresses is changed, it could also trigger the shipping quote. We had accomplished this by adding the following javascript line:
$('#edit-panes-quotes-quote-button').click();
