thank you for your feedback.

You could do this already. In the extended tax report settings you can select 2 sliders if warnings for other purchase pools are shown or even calculate gain in foreign currency.
Or you switch always in the settings between 2 currencies or you add a 2nd account and restore your data there from time to time and have this account in a different currency.

We are doing our best to add more and more blockchain importers.
