[Koha] browse shelf for serials without items

Dear Kohaers, while it is possible to assign a call number to a serial subscription, as far as I understand, it is currently not possible to have a serial shown with the "browse shelf" function, unless that serial has items (with their own, proper call numbers). I wonder whether it is possible to circumvent this limitation, perhaps adding one "fake" item to the record for that serial. (Apologies for duplicate posting to both the users and the developers lists, as I feel my question might receive either an answer based on current usage, or possibly stimulate an enhancement of the browse shelf function.) Many thanks and best regards, Giuseppe.
