EPM Automate - How to automate the download of a .out file and not fail the the calling script

I'm having 2 issues I could use some guidance to resolve. We are using EPM Automate to run a Freeform integration (runIntegration). If something fails to load to the cube, I would like to be able identify that the integration failed due to a record not loading and and automate the download of the .out file when this happens.

Right now if a row fails to load, it is failing the integration. I don't see a code to check for in my .bat file to ignore this type of failure so not to fail my script. 2nd issue, the .out file name increments and I have not found a way to know which .out file to issue the downloadFile command against. The file format is app-cubename_number.out. Using a multi-character wildcard does not appear to be an option.
