Batch processing overwrites the multiple outputs into a single output file?

I know that is an old question, but if still looking for a solution:

How to add suffix to graph write operator in SNAP GUI?

Hello Step Forum, I am going to split 20 Sentinel-1 A SLC acquired on the same track during 2017. I am using the graph builder to streamline the process in batch processing. It is a simple READ -> TOPSAR SPLIT -> WRITE graph. Is there any way in the GUI to define default output file names as for ex. [file_name]_split? So when I load 20 files in the graph, they will all be written with the _split suffix. Thank you

And probably if you deselect the ‘Keep source product name’ before loading the graph the Write tabs you show up.
