we use pick pack ship on our IF on sales order how come i cant see it for vendor return IF

This feature is limited to sales orders, no settings to enable it for VRA fulfillment to my knowledge.

any workarounds , our warehouse manger has a saved search of all the IF that have status of picked so he knows what to work on i need this to show up in the list

I suggest utilizing the Reminders portlet from the dashboard, and adding the native reminder: Vendor Return Authorizations to Return. This will provide them with a visual notification when a VRA has been created that is eligible for return.
