Auto assign request to person who made the request.

Has anyone found a way to auto assign a request to the person making the request? 

The dashboards I have made to track all of the various requests in the company filter by showing only "assigned to current user" status, this has resulted in a large number of people missing their own tasks because they forget to assign the task to themselves after making the initial request. 

If it was possible to sort the status as "assigned to current user" or "Author is current is user" rather than an and statement that would also solve my problem.

If there is no worked around for this the only other option I can see is to make two separate dashboards for tracking each request, one for the people submitting the request who would have filter by author and the receivers being filtered by currently assigned. This however would result in me managing over 20 dashboards.
