This is ofcourse possible with Service Desk 7. My suggestion is you would have to customize the Email.Monitor workflow. Then in this workflow, since the email is an input you have what is typed in the body of the email. You would then parse this for each of the mappings
i.e. Search for {HelpdeskValue} workitem_status_lookup_id = 600 {/HelpdeskValue}
Then remove any spaces, and parse the string to get what is after the = and before the { symbol. Then you know it is workitem_status_lookup_id because you searched for it and the value since you parsed it.
I know it is a pain because it doesnt do this out of the box, as HD6 did. However, this customization isnt that painful, depending on how many of the Helpdesk 6 data fields you were looking at.
