MultiBacktest - why no stats returned?

I just tried the MultiBacktest and saw that it only returns the heatmaps, but not the stats. I wonder, since it wraps the optimize function, why not return the stats for every symbol too? It is a bit difficult to see what are the optimization results without seeing all the relevant data coming out of the stats too. Any particular reason why those weren't included?

the function fingerprint could be more like Backtest, with best_stats and then heatmaps conditionally returned. 👍
