Changing the labels for stages in procurement/requisition approval workflow

Content

Hi All,

for one of our clients, we have configured the requisition/Procurement approval rules which spans multiple stages (pre-approval, terms and post approval stage). when we check the manage approval for a purchase order/requisitions, we want to know if the names which are displayed :- pre-approval stage, terms stage, post approval stage whether the labels can be changed. 

Client wants something like this

1. Buyer stage (pre-approval stage)

2. Budget coordinator stage (terms stage)

3. Management Hiearchy stage (post approval stage)

Any pointers on how to change the labels will be appreciated.
