Keyboard and Mouse for Soldier, DS4Windows for flight problems. Please Help.

Hi, I'm having problems setting up DS4 without disabling mouse and keyboard.

What I would like to achieve is to use the mouse and keyboard when I'm a soldier and to swap over to DS4Windows when flying however so far It seems as if I can only have one or the other.

I launch the game through steam and the DS4Windows works however it completely disables my mouse and keyboard, even on the options menu I have to use the DS4 to select a game, the mouse icon is just spinning and I cannot click on anything.

Is it possible to set it up in a way where I can use a mouse and keyboard to select a game and go through options etc and when I play as a soldier and just keep the DS4 ready to swap over when flying?
