Customize standard operation of standard process

Hello.

I'd like to customize a standard operation into CNSSPRSTD standard process, called by the specific processing CNSSPRSPE, about projected stock inventory.

It's possible to:

- copy the standard process CNSSPRSTD

- create a new one, called (for example) YCNSSPRSTD and customize this one?

Is it possible?

Thanks for your support.

BR
