Send sound to different audio devices in Window 10

I have multiple audio devices so I want app or programs to send sound to different devices.
for example, I want sound from game program send to my bluetooth speaker/handset but the youtube playing send to the window pc internal speaker. Any way easy to do that?
I ask this because sometimes the program will choose the wrong device and I cannot change it.

Settings►System►Sound►Advanced sound options...

Yes, that is probably what I want. Thanks for sharing.
I will have it tested tomorrow.
