Keep Single step task from completing until Dead Line date

[Rick Sample]

I have an standard task that has a Confirm on end. Started via 
SWW_WI_START. (I know, I need to change to API but not today)
This keeps the task in the inbox until the user completes or until the
Dead Line 
is reached and then terminates. 

Now, business does not like the Confirm on End pop-up. (Don't ask!) 
They want it to just stay in the inbox until the deadline date. The
user could execute 
the task several times and just not go away until dead line. 

I would rather not create a whole WF template just to loop. 
Anyone know of a way to achieve this in 4.6c?
