If you want to copy over all labels from the token, you could also use the following code in a Custom Code activity to cut down on the work of assigning all labels individually.
Note that I use "<" in the condition of the for-loop. This is done with the assumption that "item" is the last label that was added to the token (in Create Objects activity). It wouldn't make much sense to assign a reference to itself to the item so I don't copy the last label.
Object item = token.item;
treenode tokenLabels = token.as(treenode).subnodes["labels"];
for(int i = 1; i < tokenLabels.subnodes.length; i++)
{
item.labels.assert(tokenLabels.subnodes[i].name, tokenLabels.subnodes[i].value);
}
