Question: Changing tunings on JP15 7 string

Hello guys! Probably I’ll join EBMM club with JP15 7 string soon and I wanted to ask few questions about tremolo. How easy can I change tunings on it? Mostly I’m planning to jump between B standard and Drop A tunings, so nothing fancy. I know it’s floating bridge so usually changing tuning even on 1 string might take time but I’d like to hear some feedback from actual owners. Sorry this question was already asked 🙂
