Passing variables to Shell Execute in Toad automation designer

I want to call a batch script to rename files as part of toad automation flow. But we want to pass variables created in automation flow to the batch script. Please advise if this is supported.
we are using Toad for oracle version 16

ex: we create 3 variables TEMLPATE_PATH, TEMPLATE_NAME and REPORT_PATH. we we want to pass these variables to batch script called from Shell Execute

Yes this is supported.

I just wrote a word doc describing how to do it and put it in my dropbox folder.

Here's a direct link to the document.
