Scrambling Rule

Hello, I'm facing one particular challenge trying to scramble HCM data.

In this client the unique ID of a person is the PERSONID_EXT Infotype 709. This means that a person has a single PERSONID_EXT, but can have several PERNR's that correspond to a different position (this is public sector).

So we have a scenario like this:

If I use standard scrambling rule for HCM the result is something like this:

But in reality PERNR 10 and 11 are the same person so they should keep the same name.

I want to copy the standard rule and copy it or create a new one.

Any help would be welcome!

Thanks.
