Custom Status for Purchase Orders

Custom Status for Purchase Orders

Currently Zoho books has functionality to create custom statuses for Sales Orders.

Can this be extended to include custom status for purchase orders as well?  It was a great decision to add this functionality to sales orders.  

Our use case is for tracking the status of orders from overseas suppliers where we need to identify if an purchase order has been booked with a shipping line, picked up from the warehouse (not necessarily on a boat yet..) and finally 'shipped' (when it is ON the boat.  During COVID there were plenty of times when orders rolled to the next sailing and weren't actually 'on the way').  Adding custom status's to P/O's as well would be useful.
