It would be great if the option to copy circulation and fine rules could be added to Koha. It would make adding new rules much faster and much more reliable as now you need to add every rule individually to every column if you add new item types or patron categories. This can cause mistakes to happen. If you could copy already existing rules, it would save significant amount of time. It would also make mistakes less likely to happen and lower the threshold when it comes to adding new item types and patron categories. The copy setting could potentially be added to the Actions column, although if you could copy multiple rules at once it would be extremely helpful.
