You can union 'Gornja Dubrava' and 'Donja Dubrava' into 'Dubrava', 'Novi Zagreb - Istok' and 'Novi Zagreb - Zapad' into 'Novi Zagreb, 'Trešnjevka - Sjever' and 'Trešnjevka - Jug' into 'Trešnjevka' and maybe 'Gornji Grad - Medveščak', 'Donji Grad' and 'Trnje' into 'Town Center'.

East Zagreb = Istočni Zagreb
West Zagreb = Zapadni Zagreb
North Zagreb = Sjeverni Zagreb
South Zagreb = Južni Zagreb
