Dynamics CRM 365 - Business Process Flow

The Business Process Flow editor has changed for Dynamcics CRM 365.

I am trying to make a copy of the standard Opportunity Business Process Flow. I have added it to a custom solition, and then pressed 'Save as' on the BPF. The resulting copy has a prefix of 'new_', not the prefix for the solution. I feel this is a bug, but there does not seem to be a channel to report these.
