You may add a table column on WFADMIN app using application designer with the following properties:
Lable: Current Assignee
Attribute: ACTIVEASSIGNMENTS.ASSIGNCODE
showfilter: checked
Now when you enter personid and press enter in current assignee filed on workflow administration, only active assignments of specified person will be shown.
