Custom Backtest call Phase 1 multiple times before phase 2

I have a strategy that I want to call multiple times. After each call of the strategy i have buy/sell/buyprice/sellprice arrays populated manually. I would like to create the backtest entertrade, exittrade objects (i think this is phase 1?) after each call of the strategy. Then after this is complete I would like to complete phase 2 of backtest using all the trade objects created from all 3 strategies. Can someone tell me if this is possible and provide any help? Thanks!
