Cannot load aggregate from history

[clarkstachio]

How would I reload an aggregate from the eventstore event history? I would expect to have a service/method available to me from within the command handler in order to reload the aggregate. Something like

// in widget command handler
const widget = this.eventStore.reloadFromHistory('widget-12312312');

widget.doSomething(command.something);
widget.commit();

Is this use case implemented?
