Importing Profile Codes

[will.good]

Hi,

Not sure if this is possible (I don't think this is)

Can we import a new set of codes rather than have to import the whole tree again?

i.e. we would like to import 20 new codes that would sit in our current tree, which we have the right code and names set up for . I can add these to the excel template and would like to be able to import these.

The system gives the impression that this is possible, as if I was importing the excel template to just add to the existing tree I would untick this

But then this throws an error 

 

If this isn't possible - then what is the above tick box there for?
