Feature request: Subscribe to pies.
Works a bit the same as subscribing to strategies on ProQuant. One person maintains a pie with it stocks/ETFs and weightings (think about for example an ARK cloned pie) and you can subscribe to that pie. If the maintainer of the pie changes it contents and/or weightings, those changes are automatically done in your subscribed pie.
When you unsubscribe to such a pie, all pie positions are sold and the funds added to your free funds in your account.
