Optimization test - Can I use custom max like Balance max + trade time max + Sharp ratio + Profit factor + win%

Dear experienced traders

I'm doing some optimization test today. 

I find custom max in optimization and it looks like I can code something to control it. 

Also I find balance max, trade time max, Sharp ratio, Profit factor, win% looks important to my EA. 

Can I use custom max like Balance max + trade time max + Sharp ratio + Profit factor + win%? Is possible that I can code the custom max like Balance max + trade time max + Sharp ratio + Profit factor + win%? 

Thank you in advance and best wishes,
