Hello Iohan,
No silly questions here. You can ask anything. For the moment you can not import back an Expert Advisor created with EA Studio to FSB Pro, or one created with FSB Pro to place back in EA Studio.
What you can do is to build the strategy in FSB Pro. Just open a new strategy, and place the entry and exit conditions you see in the strategy in EA Studio. Place the exact methods, parameters values, SL and TP, and you will have the strategy there.
