Is there any better way to separate mouse and controller camera speed in Enhanced Input?

[JsonYeo]

In enhanced input, the default IA_Look can be multiplied by a float value “Mouse Cam Spd” I added initially. However, when I’m trying to add “Controller Cam Spd”, there are 3 options I have in mind:

1. Use another input action IA_Look_Controller, just for controllers. Brute way but works.
2. Use “Event Tick” or “Any Key” to detect controller inputs, and if there is, then multiply camera speed in IA_Look by controller cam spd, otherwise multiply by mouse cam spd. This method fails sometimes because when I set 0.1 for mouse and 10 for controller cam spd, after rotating with Right Stick, and I rotate the camera with the mouse, it did not slow down until keyboard inputs are pressed, hence it remains the same speed.
3. Casting to the scalar modifier and change by BP won’t work. idk why.
   Just curious other than the 3 mentioned ways, are there any better/optimized method?
   I’m trying to make mouse cam spd and controller’s independent.

i detect input like this:

and then use select nodes to choose different sensitivity settings based on the input:
