Mathijs Hi ๐๐ผ Mathijs,
bunq ๐ is all about making our banking lives a whole lot easier... so, your idea ๐ก would fit right in.
I would go even further then set an enddate. I would like to see it more as an extension of Travel Tips. When the app detects you are back, he could aks if you want to remove the country you added (by using Travel Tips) during your trip. So, that way it will also be similar to the flow of adding a country by using Travel Tips.
