Quick and simple way to create Bounded-Context collaborators

[Nagelfar]

When adding references to collaborators of a bounded context (could be another domain or another bounded context) only existing collaborators can be referenced.
Its cumbersome to first create a collaborator on another screen and then go back to the initial screen in order to reference it.

A simple way to create collaborators in a 'draft' mode, while not leaving the current screen is required.
