1. Create a custom form to restrict which Special Information Types (SITs) can be viewed or edited. Select the SIT to include or exclude and save the form. 2. Create a taskflow node specifying the custom form. Save the node. 3. Assign the node to the taskflow by selecting the node in the taskflow definition and removing the default "Special" node. Add the new node and save. This will restrict the SITs available to only those included in the custom form.
