Email to Request Creator

[asherwood]

I've been making some minor updates to our change request process, but have hit an issue that I can't seem to resolve. 

The change form users have asked for an automated email to be sent to inform them when their change request goes to CAB for approval. I can’t figure out in BPM how to send an email to the Request Creator. The default BPM options are Email Customer, which doesn’t work because the creator isn’t the customer, and I can’t use Email Request Owner because at this stage in the process the request owner is the Change Manager. Is there a way for me to automate sending an email to the request creator?
