configuring unreal game to different sandbox ids

My game is almost ready to be released on EOS.
It is developed using unreal engine, and we’re using Epic Online Subsystem plugin to connect to epic and send achievements.

When I upload a binary, it is linked to the dev sandbox, so makes sense that in my plugin config I set the sandbox id to be dev. but when I push it to stage how can I change the sandbox id?

should I configure 3 different artifacts in the same config?

Thanks
