The only problem you have is that PICS is a intergrated course "thing". Unless you on one of those courses you can't log it.
I would imagine that this thread has been noted and there are a few emails flying around between various national authorities.
BTW Personally I don't think they should be a night requirment for a PPL IR so don't take my comment as putting anyone down. I just cant see how they can justify/allow it to work.
