Is there a way to set the rear door locks to unlock from the locked position by using the inside door handle? With the doors locked I can pull the front inside door handle and with that motion it will unlock and open the door. This does not work the same for the rear doors. The rear doors must be unlocked before the doors can be opened using inside door handles. Is this how they're built to work or is there something wrong? I have a 2004 XC70 which I assume should be the same setup as the V70s. Thanks.
