In order to set the symbol servers across different debuggers it is best to set the symbol path environment variable.

The variable name is _NT_SYMBOL_PATH, to set the local cache to a folder user the cache*{folder} option and for each symbol server you are adding use the SRV*{server} option. Each option is separated by a ;.

Full example:

cache*C:\Symbols;SRV*https://msdl.microsoft.com/download/symbols;SRV*https://symbols.nuget.org/download/symbols
