Auto generate combined process map

One of the major strength's of Promapp is the ability to connect individual processes to show the bigger picture and create context.
To help create this, some of our teams are creating 'overview' processes which are made up of Process Links (no additional activities).

However these take a bit of time to create and manage and it would be useful if they could be auto-generated (even if they didn't have swim lanes). I've seen this done before in other process mapping tools where it draws arrows between the processes that have a relationship (through triggers/outputs).
