Hi,

every reference to an object can you convert to a number by the command tonum(thing). Then you can store this value for example in a label, a table cell and so on. Whenever you need a reference to this object, wherever the object exists in the model, you convert it back to a node by the command tonode(num value) . You get a reference to the object. The object can be an item, too. But the reference exists even if the item has gone into a sink.

If you store the number in a table you can add further attributes in the table to identify your item reference.
