Item Merge

Merge items into one.

Use this valve to merge two or more items into a single item that may or may not exist (if it doesn't exist; it is created).

If a property exist on the destination item it will be added (resulting in a multi-valued property).

Which items to include in merge can be controlled with "item_include_expr", see Item.
