Series mixed between states

Hi

This may have been discussed before, but I did not locate anything similar. Below are tokens/medals which were given for free to the attendees of yearly marches/walks around the city of Ljubljana. Till 1990 these pieces fall into Yugoslavia, later into Slovenia. When clicking on link of the series both are separated additionally by the country (or lets say "Location"). I would just like to hear if anyone finds this not OK from collectors perspective? In the end it counts which pieces you have, but still is nice to see these pieces in historical order all together.

The series can be shown on one page, it's just that the links from the individual items goes to a link for the series and the country instead of a link for the series unconstrained by country.

..not when you click on the series link from specific page...
