Do the FSI injectors need coding if they are being replaced?

Just had my injectors cleaned and flow tested.
I had them all individually tagged to what cylinder hey came from but the guy who done the cleaning didn’t relabel them and now they are all in one bag and I got no idea what ones belong to what cylinder.

I know with the TDI injectors you have to code them in so they can relearn.
Is this the same with FSI?
I can’t find anywhere in the service manual that mentions this?
