Hello John Doe,
The short answer is no, MIMWAL (and other MIM Workflow) needs that you submit the request to be trigger.
The long answer is to use another method, and duplicate the algorithm.
Can you give us some context regarding the need to display the account name to the user in MIM? If it for the Manager, you can trigger a notification activity to send a mail to the requestor for example.
BR,
Sylvain
