Business Process Flow and Project Service

Hello,

Is it possible to create a new project service in business process flow? Or do I have to use Project entity in the stage? The project entity doesn’t have same fields as project service.

Here is BPF I would like to do:

Qualify -> Develop (If Project management equals yes) ->                                          Quote ->

                                                                |

                                                                |                                                                              ^

                                                Branched to the new stage -> Project template -> etc etc .. |
