"serialNumber" property located in local user settings instead of launch.json

Is your feature request related to a problem? Please describe.
When working multiple people on the same project using SCM, it is annoying to have to resolve merge conflicts every time a new commit is made due to the serialNumber property being in launch.json.

Describe the solution you'd like
The "serialNumber" property should be located in user settings.

Have you tried removing the "serialNumber" property altogether? I'm using a J-Link and I've never had to include the "serialNumber" property in my launch.json

sorry, I should have noted that I have multiple debuggers connected to my computer, so I need to specify which one to use.

I found out that you can put custom settings in the user settings.json and reference it from the launch.json. Example:
In settings.json
"serialNumber": <your serial number>
In launch.json:
"serialNumber": "${config:serialNumber}",
