Can you clarify your example of the desired bibliography format. It seems you want to first categorize the order of the bibliography references by journal name but it’s unclear what the secondary sort field would be. Judging by your output example. it doesn’t appear to be either author name or year. So can you clarify what the order would be? It’s possible to sort the references by journal name but the additional sort fields may pose some issues depending on the data.
What you are requesting is not considered standard practice across journals but may be unique to your situation. You might also recheck the journal’s Author Submissions guideline to see if it specifically requests the bibliography be listed in a categorized format based by journal title. If not, a standard bibliography could be submitted and the categorized bibliography reference format will be attended to by the Journal’s editing/production staff.
