Open User request in Add Mode

Hi,
I have a query for WO Request with Parameter Value on the Requested_By field
with he criteria [Please enter your name]& “*�
I also have a form based on this query.
What I need is: to be able to open this form in Add Mode (I have macro-open
form for that), but that it will still ask to enter user name and that the
name will go automatically to the Requested_By field. The purpose is – create
new WO request for this user.
Is it possible?
Any help is greatly appreciated.
