I would say this is exactly what Zorros command line support is for
http://zorro-project.com/manual/en/command.htm

For example you could do something like this to run a test on two different assets changing two parameters between runs
Code:
"c:program filesZorroZorro.exe" -run myscript -a USD/CAD -i 1 -i 2
"c:program filesZorroZorro.exe" -run myscript -a USD/CAD -i 3 -i 4
"c:program filesZorroZorro.exe" -run myscript -a EUR/USD -i 1 -i 2
"c:program filesZorroZorro.exe" -run myscript -a EUR/USD -i 3 -i 4
