Is there a way to configure a SequenceStyleGenerator for use not as a identifier on an entity, but as a generator for unique numbers?
I would like a database sequence to be used for generating just a number, then put a value together by appending the sequence value to a string like A-100, A-101, B-102...

We wanted that too and implemented it by using a trigger. But we have to perform a refresh afterwards (if we want to work with that saved entity). We did that by a custom annotation which is being interpreted by our persistence layer.
