You can let stay an item after ending of the dwell time, if you don't transport the item or you don't pull the item. An other approach doesn't use a discrete dwell time. Instead the item isn't released by the dwell time option "Do Not Release Item". Then you have to execute the command releaseitem(obj item, num port) in an event of your own. Typical self created events are delayed messages. You send a delayed message and you check if the item dwell is reached then you release the item or you send another delayed message when you want to check the release again. In cases where you release an item before a pending message will be received you must prevent the later event to release the item at all. You check such situation by comparison of the object where the item actually stays with the rack.

Attached is an example in FlexSim 7.5.4, which you can open in 7.7.4
