Using a Grails "g:sortableColumn" to sort by the size of a "hasMany" (many to one) property?

is it possible to use the Grails "g:sortableColumn" tag to sort by a domain class "hasMany" property count?

class Book { hasMany = [authors: User]}

I want to sort all Books by the number of authors with a "g:sortableColumn" tag in my view, but how? Realy not possible?

Thanks and best regards...

not the best solution, but one

I thought there was a way to do it with criteriaBuilder but I cannot seem to make it work without changing your domain object
