I don't think you can do that with Floating IP. I totally understand what you mean. I had the same question at the beginning.
You have to create another network and use your Floating IP on the new network. Then attach that network to your instance by creating a new port and attaching it to the instance.
What I usually do is create a internal network and a external one.
See the diagram attached.

please try to explain with more details what you're trying to do, the effect you want to achieve, your setup.
I believe (s)he wants to assign public IP directly to instance (instead of private and mapping floating IP to it).
