XLS Format Collector (branch safe)

Iteratively merges and stores XLS Formatter model settings within a loop

This is used in conjunction with an XLS Format Collector component. The Collector is placed within a LOOP and stores the collected XLS Format models with each loop iteration.

The XLS Format Retriever is placed after the LOOP END, and collectors the stored XLS Formatter model so that it can be passed to the XLS Format (Apply) node, or other XLS Format nodes.
