Backtest Analysis by Multiple Risk-Reward Ratios

I would like the backtesting program to allow me to run all my trades using a fixed risk-reward ratio (for example 1:2 or 1:4), but then in the results analysis, I would like to see what my win rate would have been if those same trades were evaluated under different ratios (such as 1:1, 1:2.5, 1:3, etc.).

This feature would help me compare outcomes across different risk-reward ratios and identify which ratio works best for my trading strategy.
