If you know which step Kel Varsen is going to be involved with, then you can set a flag in the data,using a SetValue, before the User step to update the data being merged with the form template and have some script on your form that checks for that flag.
If you don't know which step Kel Varsen is going to be involved with
then you would have to change the data flag in the render service associated with the xfaForm variable. When you create/use the render service associated with the form, you can add an extra input parameter and pass the user name. Then in the render service, you can set that flag in the data (or not) and have the form react to that flag.
