restart robot in backtesting

Hi 

in order to fine-tune a strategy you may want to back test it with different settings in order to come with the set of values that gives the maximum return.

Is there any possibility to automate this in calgo?

for instance start with a value of a parameter, save results in a file, then restart on the same time frame with another value of that parameter, save the results and continue in a loop? 

Thank you
