New feature wanted!! Combining multiple strategy balance chart

Dear Popov n forex team.. I already make some profit for using FSB in last 1 years.. but I'm not satisfied enough cause I need some additional feature in both FSB n FSB PRO...

Suppose I have 4 strategy, each produce geometric yearly return of 23%, n equity drawdown of 30%.. Then I face with some dilemma, if I increase my position in each of 4 strategy, I can increase my yearly return.. but the PROBLEM is I want to know, if I use that 4 strategy is my drawdown equal, less, or more than 30%..

So.. please forex team can u make feature that combine multiple strategy account balance chart?? so people who create many strategy can know, what is their combined strategy equity drawdown if they use that combined strategy
