You should be able to apply screen personalisations to the Leave & Absence Workflow button, thereby renaming it something more user-friendly, such as "Approval options".

Currently you can right-click the button and rename it, but on refresh, it reverts to its previous title.

The same goes for the drop-down options below the button, as well as other buttons of this type that found all over Dynamics.

Thank you for your suggestion. After careful consideration, we’ve decided not to proceed with this functionality at this time. In 2020 release wave 2, there are leave and absence workflow enhancements planned that will help with the terminology used for workflow.  This posting is provided “as is” with no warranties, and confers no rights.
