'Baking' Elements from GH to ArchiCAD

Hi all,
I have my GH definition and it basically creates a façade in front of my wall and I am happy with that. Now I would like to bake those elements into ArchiCAD (not Rhino :wink: and move on. How to achieve this most effectively? Braking the connection will not do as I intend on using the definition on other walls in the same AC file and I don’t want to overwrite the elements already created. The incremental process is preferred rather than loading all the walls into GH at once (stability-wise and small manual adjustments are the main reason). What’s your best practice. How can I make an object forget that it was born in GH?
