[pulseaudio-discuss] How to choose the sound card for an application using CLI ?

I want to run applications with specifics sound cards in command line on 
Ubuntu 20.04.
I know it is graphically possible with Pulseaudio Volume Control which 
let me choose the card in a menu after the application is launched.
But I want to use command lines so that I can automatize the process in 
a bash file (I've got ten sound cards and more to come).

I've tried "pactl set-default-sink" but it changes the card for all the 
I've looked in "man pulse-cli-syntax" but I didn't find what I'm looking 

I've also tried to use environment variables such as ALSA_CARD= and 
ALSA_PCM_CARD= without success.

Is there a way to do what I want ?

Thank you.
