A few questions about shipping

Hello,

I am a new seller on Amazon EU and i want to ship products from our company in Japan to Amazon centers in France and Germany. What is the best way to do that?

I have listed my products on the Germany marketplace and French marketplace using different skus. As far as I understand, it is not possible to create a shipping order for both those countries at the same time and I would have to create separate shipping orders (one from Japan to Germany and one from Japan to France). Is it correct?

The CEO of my company asked if we could just ship everything on the same boat to save money but i don’t think it is possible.I am a a bit lost and any insights would be greatly appreciated.
