If you're using the Request approval task, you won't have that option. You'll need to instead use an Assign Flexi task. Then you'll have the option to customize the outcomes. You can change the existing ones, and even add your own options.
I have added pending to my outcomes.
I also modified my workflow and I added a state machine so if the pending is selected it wait for 1 day and it will send out the notification again.
But my Pause FOr doesn't work, seems like a sharepoint issue:( any idea how to solve that issue? when it goes to pending it get stuck there in Pause for and it won't move on.
There is a document in the forums here that discusses problems with the Pause For and possible solutions. The link is here:
