Yes, but not easily. You would have to edit the
card.php file found here:
Add this where you want the numbers:
if ( $atts['show_phone_numbers'] ) $entry->getPhoneNumberBlock( array( 'format' => $atts['phone_format'] , 'type' => $atts['phone_types'] ) );
Save the file and upload it.
If you choose to do this, then I highly recommend following this QuickTip on where to upload the new file so it is safe from being overwritten during updates to Circled.
Hope that helps!
