Thanks.
I experemented but my T1 doesn't create the series from the new column - and I adjusted the SONY T1 driver in calibre to create collections also from the new column.
The collections of that series column aren't created.
So I decided to make all more simple: Only a point "." at the start of a series-collection like ".Star Wars" - without the extra word "(series)". That function very well.

I also saw that the guy who makes the root wanted to create a special view for series:

I want to thank you very much for helping me!

Maybe in future I also can help people - I hope so.
