Add additional Funtions in COHV- Delete Planned Orders

Hi,

I have a requirement to Close the Planned Orders via COHV using mass processing. Issue is, I dont see this function in the mass processing tab. There are only 2 functions currently available for Planned Orders, 1)Convert Planned Order 2) Material Availability check.This is probably because of the Enhancement Package that we are using.

My question is how to add other functionalities like in the mass Processing:

Firm/unfirm planned orders

Delete planned orders
Enter confirmations against REM planned orders

Appreciate your quick response
