Isn't there remote key concept for Hierarchy lookup Tables?

I don't see the [remote key] field in destination items.?

I really don't intend to use this remote Key concept in syndicating back to the source system, but specifically to satisfy this operation need:

I have a hierarchy table with two fields and both of them need to be display fields, Code & Name for Business reasons.

So when loading in the hierarchy field at main table level, I don't have to go through this compounding effort and just map the remote key which is just the code and not the name?
