Prevent Step back in workflow

[B_Stockwell]

I have an activation workflow with an or split that on the "don't activate" uses the participant chooser to let the initiator know (in their inbox) that their approver didn't activate the page. The user gets a message that "The story was not approved" in their inbox, but this is treated like an actionable step--I'd prefer if the user were unable to use the "Step back" option, and the workflow be terminated. 

Is there a way to trigger a notification to the initiator (or any given participant) without it being treated like a advance/backtrack step?
