How to Stop a Basic Table Output overwriting itself

[bacon1983]

Hi There

I have workflow with 4 basic table outputs each supported by a render  (see Screenshot 2 for render setup

How do I ensure that if the ouytput file already exists, then the WF tool will fail on output, hence stopping the file being overwritten.  This would be the same functionality as selecting 'Create New Sheet' as a .xlsx output option.

Not sure how to do this with Render Tool

Maybe we can move the files after creation using Block Until Done
