[Koha] cross-links in analytics

Hi, when a "Link to host item" is added to a constituent record, the appropriate 773 Marc datafield is created in the constituent record, and populated with the appropriate subfields referring to the host item. Then, the OPAC for the constituent record does show the link to the host record. The converse seems not to be the case, i.e. no corresponding 774 Marc datafield is created in the host record, and no link appears in the host record's OPAC. Is this a feature, is it my mistake, or a bug? Many thanks and best regards, Giuseppe. P.S. I am aware that this issue has been issued before (also in this mailing list), but I could not find an answer.
