Unable to register metrics for multiple outputs

[lewellien]

Hello,

i have multiple outputs of the same type (prometheus_remote_write)
But after registering the second one i get an error that the metrics are duplicated and cannot be registered.

Is it possible to include the name of the output as a label, so the metrics would not be duplicated?
Relevant Logs:

[prometheus_write_output] initialized prometheus write output
