Zanussi dryer auto sense prevents full drying

My Zanussi tumble dryer has an auto sense facility which senses when the clothes are dry and stops the machine. The trouble is on items like duvets, padded coats and pillows it does not sense properly and stops when the interior feathers are still damp, so you never get a dry fluffy pillow or coat or duvet. Does anyone else have this machine facility and have you found a way around it, i.e. turning off the auto sense? thank u.
