How to macerate a perfume

I wanna know how to do it effectively, I wanna ask few questions

1) How long should I macerate a fragrance? 2) Where to store it during maceration? 3) Can I use it during this period? 4) Does the bottle needs to be kept stable and not be moved (asking bcoz I store me bottles in drawers and the liquid moves when I pull the drawer to access a bottle)? 5) Does this increase projection? 6) Should I macerate a perfume I already like, can things go wrong?

Any other advice is dearly appreciated 🙏
