Replicated attributes in CDM to LDM generation

I thought this was a problem with generating the PDM from the LDM, but when I looked back the replicated attributes were actually introduced during the CDM to LDM generation.

So, my question is if I have attributes in a super type entity in a CDM, how to I prevent them from being replicated in all the subtypes when I generate the LDM?

I'm in PowerDesginer 16.5.4.3
