I have some strat that are performing well in real and i would like to keep them.
so when i want to add some strat to the old ones, i would like that portfolio builder could keep them and add only 1 or 2 or whatever i select to them from a selection of new other strat. i attach you a screenshot:
you can merge strategies which you want to left to a portfolio, from portfolio make a simple strategy and you can add new ones...its not 100%, but it works
