Thank you Axel!
Your solution indeed gives the result I was looking for. I suppose there
is just no more elegant way to do this. But maybe that's a good thing,
as I am not sure anymore, I my idea was a good one in the first place.
Maybe it would not be clear enough to easily understand such grouped
keys. But thank you anyway for your help.
Regards.
