Hi Afra,
Unfortunately not, we are going to make some significant changes that will make international duty much more straightforward. It would be worth subscribing to updates on the feature request for Expansion to customisable Duty tool.
In the meantime, if there are any reports you would like us to look at, if you can put them forward as a feature request, our dev team can review them to see if it is possible to make them for you. If you can include as much detail, e.g. the headings you would want to see or any specific criteria for reporting, it really helps.
