Multiple Find dialogs

I am running multiple IntelliJ IDEA instances on multiple screens in a huge project where I am doing refactoring of different parts. Hence, some part of the project is shown on one screen in one IntelliJ IDEA instance. Another part is shown on another screen in another IntelliJ IDEA instance.

However, it looks like the Ctrl-Shift-F Find dialog can only be opened once per computer, not one per IntellJ IDEA instance. Can this be configured otherwise?
