In the OOTB 2007 Approval Workflow, users had the choice whether to allow reassignment of a workflow task and/or whether to allow the approver to request for a change. These options were presented as two checkboxes in the 2007 template. How is the option to disallow these behaviors acheived in the OOTB 2010 version of the Approval Workflow? 

Edited: I should have clarified that few end users have access to SharePoint Designer in our environment, so I was looking for a method to allow users to specify this from the UI.
