Different Budgets should not share periods

I have 2 different budget books for 2 very different purposes. On one I want to see a time span of more than 2 years, on the other I want to see only the current month.

Every time I switch between budgets, I need to manually adjust the periods because they are not remembered since the last adjustment on each budget. I end up not doing it and miss many insights that I love seeing.

Thanks for considering!
