Runtime event with multiple event sources.

Hello,

I need to launch workflow process when some events fired. By example: I need to launch an update on Account when address from account is modified or note on want account is modified or created. Runtime Event seems to be good process. 

Then I create a workflow process with start step and other action step. Then in order to create both event,  I create one connection from start step with information about address event and a second connection from start step with information about  note event.

Workflow Validation is OK. After deployment two events have been created: OK.

But when I trigger my event by address modification, an error appears because I can't define two connections from start step.
