This feature is really needed for exactly that usecase.
I have two accounts where I have traded both automated eas and my manual trading.
It's such a pity that I can not split my account in exact this situation.
My manual trading results speak for itself and of course the ea results are a mess.

Where I only trade on a manual basis and strategy.
I think my example really shows that on the long run there is only one
Real solution to get consistent profit in forex ---> Manual Trading with a proper strategy and discipline.
