Virtual joysticks for mobile possible? (Mimic controller left & right analogs)

Hey,

I am at the beginnings of this mobile game I am creating, and at the moment it works like a twin stick shooter, left analog to move and jump - with the right analog to shoot with.

Now all the controls work well with all a PS4 controller analog, and I am at the stage where I would like to port it to mobile (android)

Is it possible to have virtual analogs on the screen that will directly mimic the input for joysticks I have set up in unity? Will make it a lot quicker as all my current programming will cross over!

Thank you.

Stephen.
