Such a feature is sadly still missing on the overview page from all the individual doujins, games etc. I reported an issue on the "A Jellyfish Girls Very Sweet Pet Mating Diary"
(click) cg set in the comment section 3 days ago and nothing happened since then. With this feature the respective publisher - in this case MediBang! - could be informed if something went wrong when uploading the doujin oder cg set.
