I am halfway through now with the help of the manual and able to create the custom HOLD statuses, however SLA does not seem to stop even though the request goes to "Held by xyz,abc". I will post the answer for SLA once I get it sorted from support
Under request header
=========================
<st_3000>Hold</st_3000>
<st_3001>Awaiting User Information</st_3001>
<st_3002>Pending User Confirmation</st_3002>
Under request item
===========================
<st_3000>Hold</st_3000>
<st_3001>Awaiting User Information</st_3001>
<st_3002>Pending User Confirmation</st_3002>
Under request_item_fulfillment_action
===========================
<custom_menu current_status_value="3001">
<st_3001 statval="3001"/>
</custom_menu>
<custom_menu current_status_value="3002">
<st_3002 statval="3002"/>
</custom_menu>
