I'm attempting to build a MoreCore extension, but \campaign\record_char.xml contains a tabs_charsheet with no name. Doesn't this make it impossible to replace or delete this element via merge? The tabs_charsheet in the 5e record_char.xml by contrast is named, making it easy to apply a merge rule to it without needing to replace the entire file. (This is still pretty new to me, though, so it's possible I'm missing something.)
